摘要
We present results of a calculation of critical temperatures of ordered GdX compounds with CsCl structure (X = Mg Rh, Cd. Zn, Cu, Ag, TI) within the Heisenberg Hamiltonian. The pair exchange interactions were evaluated using a parameter-free method based on the magnetic force theorem. The resulting critical temperatures are compared to experiment:, they exhibit strong sensitivity to computational details. (c) 2006 Elsevier B.V. All rights reserved.
