Magnetic and Magnetostrictive Properties of the Er(FexCu1−x)2 Compounds

Abstract

Ferrimagnetic compounds of the series Er(FexCu1−x)2 (x  1.0, 0.95, 0.9, 0.85, and 0.8) are investigated by magnetization, a. c. magnetic susceptibility, Mössbauer effect, and magnetostriction measurements. With decreasing x‐value, the Curie temperature, the effective iron moments as well as the average magnetic moment of the iron sublattice decreases monotonously.
