Abstract

Intermetallic compounds of HoMn6-xFexSn6 (0 <= x <= 1.2) were studied by means of field-cooled (FC) and zero-field-cooled (ZFC) magnetization measurements in the temperature range 5 K <= T <= 600 K. The unit cell parameters decrease with the increasing of Fe content. The compounds with x= 0 and 0.3 behave ferrimagnetically in the whole temperature range and spin reorientation transition is observed at 200 and 185 K, respectively. The x=0.5 and 0.6 compounds show ferrimagnetic-helimagnetic-ferrimagnetic phase transitions with decreasing temperature while the compounds with x=0.9 and 1.2 only show helimagnetic-ferrimagnetic phase transitions. Additionally, for the x=0.6 compound the metamagnetic phase transition from helimagnetism to ferrimagnetism is induced by an applied field 20 kOe. (C) 2006 Elsevier B.V. All rights reserved.
