Abstract

HoAl2 exhibits a first order spin reorientation transition at 20 K. Heat capacity measurements showed that when Ho is partially replaced by Er in Ho1-xErxAl2, the spin reorientation transition is gradually suppressed, while slowly shifting to higher temperatures with increasing Er concentration. In this paper, we investigate the magnetic properties of pseudo binary Ho1-xErxAl2 alloys by ac and dc magnetization measurements. The magnetization data show that the magnetic interactions below T-C are dramatically modified when Er is added in Ho1-xErxAl2. For a better explanation of the experimental data, results of first principles calculations have been presented as well. (c) 2013 American Institute of Physics.
