摘要

In order to solve a serious problem of understanding the magnetic properties of UCu2Si2, we have grown single crystals of this compound from Cu-flux. Here we focus primarily on the magnetic behavior of this compound. In contrast to some previous polycrystalline and single-crystalline reports on UCu2Si2 no signs of the transition into anti ferromagnetic behavior have been observed below T-C = 104(1) K. The magnetic properties of this compound are highly anisotropic, with an easy axis of magnetization along the [001] direction. The saturation moment has been determined at 4.2 K to be 1.55 mu(B). In the paramagnetic region the effective moments for the easy and hard directions are both about 3.0 mu(B). An extensive discussion of the obtained data, compared to those recently published by Fisk et al. and Matsuda et al., also based on single crystalline materials, has been presented. No an anti ferromagnetic phase above T-C has been detected. (c) 2006 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.
