UGe2 是一种铁磁重费米子 (HF) 超导体,可在 1.0 至 1.5GPa 的压力下提供超导性。在本文中,我们在大气压下进行了高达 27 T 的详细磁化实验。沿 a 轴的磁化表示典型的铁磁特性。另一方面,沿 b 轴的磁化强度比容易的 a 轴的磁化强度小很多。磁晶各向异性常数与稀土铁磁体Nd2Fe17相同,这表明UGe2是一种高度各向异性的铁磁体。
UGe2 is a ferromagnetic heavy-fermion (HF) superconductor, which provides superconductivity under pressure in the range of 1.0 to 1.5 GPa. In this paper, we conducted detailed magnetization experiments up to 27 T and at atmospheric pressure. Magnetization along the a-axis indicates typical ferromagnetic property. On the other hand, magnetization along the b-axis is quite a bit smaller than that of the easy a-axis. The magnetocrystalline anisotropy constant is the same as the rare earth ferromagnet Nd2Fe17, which indicates that UGe2 is a highly anisotropic ferromagnet.
