Abstract

Mössbauer studies of extremely dilute ¹⁵³Eu in SmM₂(M = Fe, Co, Ni) yield the magnetic hyperfine fields [- 1090(20), - 1250(20), - 450(100) kOe] and electric field gradients [1.40(10) × 10¹⁸, 1.35(10) × 10¹⁸, ≁0 V/cm²) acting on the Eu nuclei. From these, the exchange fields acting on the Eu³⁺ ions were found to be μ_BH_exch/k = 105(10), 100(10) and 15(2) K.
