摘要：

X-Ray powder diffraction method is used to investigate the effect of magnetic ordering and external magnetic field on crystal structure of Laves phase intermetallic compound ErCo2. The diffraction patterns were recorded at temperatures from 300 K down to 8.5 K in magnetic field up to 5 T. Distortion of the room-temperature cubic structure was found in magnetically ordered state below 32 K. The symmetry at low temperature is rhombohedral in agreement with literature results. Or lower symmetry than it. However the symmetry of the unit cell increases to cubic in external magnetic field of 5 T. (c) 2006 Elsevier B.V. All rights reserved.
