摘要：
Structural studies by means of powder X-ray diffraction and single-crystal neutron diffraction show that URhGe crystallizes in the orthorhombic TiNiSi-type of structure. Combined magnetic. electrical-transport and thermal studies performed for the first time on a single crystal confirm ferromagnetic order of URhGe below 9.6K. In contrast to previous powder neutron-diffraction experiments. our single-crystal results point to collinear ferromagnetic order of U moments of 0.35+/-0.08 mu(B) confined to the b-c plane. i.e. with no component along the a-axis, which is the hard-magnetization direction in URhGe. Our findings regarding the magnetic properties are in good agreement with theoretical first-principle calculations. (C) 2002 Elsevier Science B.V, All rights reserved.
