 note = {Magnetic excitations in the antiferromagnetic Bi₂CuO₄ (TN=42K) are investigated on the basis of anisotropic exchange interaction between spins of Cu²⁺ ions. We calculate the dispersion curves and evaluate the intensity of the inelastic neutron scattering by spin wave excitations. The results are discussed in connection with observations. Spin contraction at 0K, temperature dependence of the sublattice magnetization and field dependence of the antiferromagnetic resonance frequency are calculated. Furthermore, the effect of spin wave interaction on the spin wave dispersions is investigated in the framework of the random phase approximation., Article, 信州大学理学部紀要 29(1): 9-20(1994)},
