Abstract
Magnetic anisotropy energy of antiferromagnetic Bi2CuO4 (T-N = 42 K) c aused by dipole-dipole interaction and anisotropic exchange interactio n is studied. By calculating the lattice sum of magnetic dipole-dipole interaction, it is found that this interaction makes the easy directi on along the c-axis, contrary to experiment. We discuss the anisotropi c exchange interaction on the basis of the orbital level splitting of Cu2+ ion due to the crystalline electric held. (C) 1998 Elsevier Scien ce B.V. All rights reserved.
