Magnetism of ErNi(2)B(2)C investigated with a two-ion model for rare-earth antiferromagnets
Result description
A two-ion model for rare-earth antiferromagnets was employed in the present work to study the magnetic and thermodynamic properties of ErNi(2)B(2)C, and derive an analytic formula for the Neel temperature of the compound with the quantum perturbation theory. To apply the theory, four new base functions had to be composed due to the special forms of its crystal-field (CF) wavefunctions. Our theoretical analysis suggested that the magnetic behavior of the compound be governed by these low-lying CF levelsin the temperature region at least up to 100 K. (C) 2011 Elsevier Ltd.
