Magnetic frustration in the high-pressure Mn2MnTeO6 (Mn3TeO6-II) double perovskite

A new double perovskite Mn2MnTeO6 has been obtained by high pressure phase transformation of a corundum-related precursor. It is antiferromagnetic below 36 K and develops a magnetic structure with magnetic moments of 4.8 μB and 3.8 μB for Mn2+ at the A and B sites respectively. This new polymorph ac...

Zusammenfassung:	A new double perovskite Mn2MnTeO6 has been obtained by high pressure phase transformation of a corundum-related precursor. It is antiferromagnetic below 36 K and develops a magnetic structure with magnetic moments of 4.8 μB and 3.8 μB for Mn2+ at the A and B sites respectively. This new polymorph accounts for a recently reported decrease in the bandgap of Mn3TeO6 under pressure that may lead to useful light-harvesting properties.
