Chemical compound

Manganese(II) telluride is aninorganic compound with thechemical formula MnTe. It is a gray solid obtained by the reaction of the elements.

Properties

[edit]

Manganese telluride crystallizes in theNaCl structure motif.[2][3]

Long thought to beantiferromagnetic, manganese telluride has been determined to bealtermagnetic.[4] It has aNéel temperature of 307 K, meaning it does not need exotic temperatures to maintain its altermagnetic ordering.[5]
