Variations of structure and magnetic properties in UTGe hydrides (T = late transition metal)

Abstract

Hydrogenation of UTGe compounds results in formation of stable alpha- and beta-hydrides, and modification of the crystal structure and magnetic properties. T-C ( 3 K) of UCoGe increases up to 50 K in beta-hydrides and T-C (9.5 K) of URhGe up to 17 K in alpha-hydrides.

The type of magnetic order is changed in UNiGe-H and UIrGe-H. The observed effects are attributed to the increased U-U spacing in the hydrides.
