Abstract: We investigate the electron spin effect on quantum states and magnetoconductance in a magnetic quantum antidot with inhomogeneous distribution of the magnetic field. It is shown that the interaction of the electron spin with the inhomogeneous magnetic field results in further splitting of the energy levels. The predicted value of the splitting is closely related to the angular momentum quantum number and the parameters of the magnetic quantum antidot. Spin-dependent magnetoconductance is very different from that in the case where the spin effect is not included. More and shallower dips appear in the spin-dependent magnetoconductance spectra.
