  • Broadening of magnetocaloric effect at elevated temperatures in nanocrystalline ZnFe2O4 thin films

    Results in Physics (Elsevier)

    Published in a peer-reviewed journal with an impact factor of 5.3 (2024).

    Abstract:
    The detection and characterization of the Magnetocaloric Effect (MCE) at the nanoscale and its subsequent impact on next-generation cooling on-chip devices are of paramount importance. Here, we demonstrate that the MCE properties housed within a ferrimagnetic phase arise in disordered ZnFe2O4. The robustness of the MCE in terms of magnetic entropy change ΔSmax (=0.07–0.09 J/kg-K at 0.5 T) emerges in…

    Abstract:
    The detection and characterization of the Magnetocaloric Effect (MCE) at the nanoscale and its subsequent impact on next-generation cooling on-chip devices are of paramount importance. Here, we demonstrate that the MCE properties housed within a ferrimagnetic phase arise in disordered ZnFe2O4. The robustness of the MCE in terms of magnetic entropy change ΔSmax (=0.07–0.09 J/kg-K at 0.5 T) emerges in ZnFe2O4 thin films at larger temperature ranges 425–710 K, reaching above room temperature. By fitting the magnetization vs. temperature curves with a Gaussian-type distribution, we observed a correlation between the broadening of the MCE peak, Curie temperature (TC) distribution, and grain size distributions in nanocrystalline ZnFe2O4 thin films. The width of TC distributions increases (up to 150 K) and consequently, the ΔS curves show an extended full width at half maximum, resulting in larger relative cooling power (RCP), and a wider change in specific heat capacities (ΔCP) and adiabatic temperatures (ΔTad). This study reveals that tuning the relative strengths of the sublattice spin configuration of antiferromagnetic (AFM) ZnFe2O4 through in-situ and ex-situ heat treatment paves the way for the alteration of MCE properties.

    Abstract:
    The novel magnetocaloric thin film material with a tunable magnetic transition is the cornerstone of magnetic refrigeration, which plays a crucial role in cooling on-chip devices. Zn-ferrite (ZnFe2O4) occupies a significant place due to its interesting grain size-controlled magnetism. In this study, we investigate the magnetocaloric properties of Zn-ferrite layers consisting of a mixture of superparamagnetic (SPM), ferrimagnetic (FiM), and bulk-type antiferromagnetic (AFM) grains. Due to the co-existence of different magnetic grains, a crossover from the conventional magnetocaloric effect (MCE) to the inverse magnetocaloric effect (IMCE) is observed. The magnetic entropy change (-ΔSM) exhibits high-temperature positive values around the Curie temperature (TC) and low-temperature negative values around either the Néel temperature (TN) or blocking temperature (TB). The maximum value of -ΔSM (0.10 J/kg K) is almost double in AFM-dominant samples compared to SPM-dominant samples, while maintaining a relative cooling power (RCP) of 11.57−14.82 J/Kg under applied fields of 0−2T. FiM-dominant samples, with a wide working temperature window around room temperature, are suitable for large RCP applications. Thus, the discovery of new IMCE materials like single layers of Zn-ferrite is equally important in the search for suitable conventional MCE materials for magnetic refrigeration devices, which can exhibit multiple -ΔSM and RCP peaks in low and high temperatures.

    From multicomponent high-entropy alloys (AlCoCrFeNi) through ternary alloys (CrFeNi) to binary (NiCr) alloys, Cr doping plays a critical role in altering the magnetocaloric properties of the resultant alloys. Magnetocaloric effect (MCE) of Ni100−xCrx (x = 5, 10, 15 at.%) nanogranular thin films were investigated by varying Cr concentration, which demonstrate near room-temperature magnetic entropy change (− ΔSM = 0.08 J/kg K) and relative cooling power (RCP = 25 J/kg) at 10 at.% Cr. The MCE properties are well predicted using a phenomenological model based on magnetization as a function of temperature, and they correlate well with experimentally measured magnetic isotherms.

    Abstract:
    Zn-ferrite is a versatile material among spinels owing to its physicochemical properties, as demonstrated in rich phase diagrams, with several conductive or magnetic behaviors dictated by its cation inversion. The strength and the type of cation inversion can be manipulated through the various thermal treatment conditions. In this study, inverted Zn-ferrite thin films prepared from radio frequency magnetron sputtering were subjected to different in situ (in vacuum) and ex situ (in air) annealing treatments. The temperature and field dependence of magnetization behaviors reveal multiple magnetic interactions compared to its bulk antiferromagnet behavior. Using the magnetic component model, the different magnetic interactions can be explained in terms of superparamagnetic (SPM), paramagnetic (PM), and ferrimagnetic (FM) contributions. At low temperatures, the SPM and FM contributions can be approximated to the hard and soft ferrimagnetic phases of Zn-ferrite, respectively, which changes with the annealing temperature and sputter power. Distinct magnetic properties emanating from in situ annealing compared to the ex-situ annealing were ascribed to the nonzero Fe2+/Fe3+ ratio, leading to the different magnetic interactions. The anisotropy was found to be the key parameter that governs the behavior of annealed in situ samples.

    Published in a peer-reviewed journal with an impact factor of 3.674 (2020) and a five-year impact factor of 4.604 (2020).

    Abstract:
    Understanding the effects of interparticle interactions is a vital problem because magnetic nanoparticles showcase a variety of magnetic configurations due to different contributions to their total energy. To derive reliable and robust properties from magnetic nanoparticles, it is thus necessary to understand the competition between particle anisotropy and interparticle interactions that define the magnetic state of nanoparticles, where size control plays an important role. Here, we apply the random anisotropy model (RAM) that considers various magnetic interactions to selectively prepared NiCr nanostructures (NiCr dense nano-clusters, nano-granular NiCr thin films, and Ag(NiCr) nano-composites) with different interparticle interactions. The estimated single-particle magnetic anisotropy K values (2.82 – 12.3 × 10^4 J/m^3) and careful analysis of magnetization behavior for these nanostructures reveal that orbital hybridization, surface segregation, and interface character govern the magnetic interactions among nanoparticles. Our study demonstrates how magnetic behaviors vary in these different magnetic systems consisting of superparamagnetic (SPM) and ferromagnetic (FM) contributions specific to magnetic interactions.
