Abstract
Magnetic excitations in the antiferromagnetic Bi2CuO4 (T-N=42K) are in vestigated on the basis of anisotropic exchange interaction between sp ins of Cu2+ ions. We calculate the dispersion curves and evaluate the intensity of the inelastic neutron scattering by spin wave excitations . Spin contraction at OK and the effect of spin wave interaction are s tudied.
