Abstract

Shape magnetostriction measurements along the [001] direction were carried out for dilute rare-earth bismuthides; LaBi: R (R = Ce, Sm, Gd, Tb, Er) and the antimonide LaSb: Gd. The magnetostriction of LaBi: Ce and LaBi: Sm reveal the "reverse magnetostriction" phenomenon, enabling us to extract an overall crystalline field splitting of 12 K for the former compound. The magnetostriction of LaBi: Gd and LaSb: Gd which are significantly larger than that of the "pure" hosts, can be explained by a modified version of a model previously suggested by us. The fitting procedure yields magnetoelastic coupling constants for LaSb: Gd and LaBi: Gd which has the correct sign and magnitude according to existing theories.
