New magnetic compounds with Heusler and Heusler-related structures

Magnetic and structural properties are presented for new ferromagnetic compounds of the form Rh2Mn X where X is Al, Ga, In, Tl, Sn, Pb, and Sb. The exchange is described in terms of competing ferromagnetic Mn-Rh-Mn interactions and antiferromagnetic Mn-Mn interactions. © 1976 The American Physical Society.
