Magnetic Properties of Fe3MnTm and Some Related Intermetallic Compounds

摘要

The magnetic properties of intermetallic compounds of stoichiometry Fe3MnR, where R is Y, Tm, Er, Dy, or Ho, have been measured in fields up to 14 kOe at temperatures ranging from 1.4° to 300°K and in fields up to 80 kOe at 4.2°K. The moments of the Mn and R atoms are in opposition to those of the Fe atoms so that a compensation point is observed for Fe3MnTm. When Fe3MnTm is cooled in a weak field from 300°K through its compensation point at 60° to 4.2°K the magnetization reverses and a field of 25 kOe is required to reduce it to zero.
