摘要:
Tetragonal ThMn12-type single crystalline ErFe11Ti and HoFe11Ti samples have been investigated by magnetization measurements and by observations of the magnetic domain structure at various temperatures between 10 and 300 K. The magnetic structure of ErFe11Ti changes from room temperature "easy axis'' (c-axis) type to conical at spin-reorientation temperature T-SR = 50 K. The HoFe11Ti has a metastable anisotropy energy minimum in the a-direction at T < 40 K. It leads to a first-order magnetization process detected by magnetization measurements along the a-axis in this temperature region. (C) 2005 Elsevier B.V. All rights reserved.
