Electronic properties of UCuSn

PDF Version Also Available for Download.

Description

Crystallographic analysis shows that UCuSn does not form in the hexagonal CaIn{sub 2} structure as reported previously, but is an ordered ternary compound and forms in an orthorhombic structure. Bulk and neutron-diffraction measurements reveal that UCuSn orders antiferromagnetically below 60 K. At 4.2 K, high-field magnetization reveal a complex magnetization process with two metamagnetic transitions. Furthermore, bulk investigations show an additional anomaly at 25 K, but a regular temperature dependence of various magnetic peaks down to the lowest temperature gives no evidence for a second magnetic transition. Possible scenarios responsible for the drastic changes in the electronic properties around 25 ... continued below
