Structure and magnetism of a new series of UTSn hydrides
چکیده انگلیسی
We studied crystal structure and magnetic properties of UCoSnH1.4 and URuSnH1.4 hydrides. They adopt the same hexagonal structure as the parent compounds. Both compounds remain ferromagnets after hydrogenation, but the tendencies of the magnetic properties differ: UCoSn exhibits a more typical behaviour expected for intermetallics of uranium upon hydrogenation (TC increases from 82 to 102.5 K, the spontaneous magnetic moment increases from 0.64 to 0.70μB /f.u.), but the influence of hydrogen absorption on URuSn is surprisingly opposite (TC decreases from 54 to 51 K, its magnetic moment gets reduced to 0.48μB /f.u. in URuSnH1.4 from 0.53μB /f.u. in URuSn).
