Spin Splitting Effect on de Haas-van Alphen Oscillation in Two-Dimensional Two-Band Systems
Abstract
We study the effects of the spin splitting due to the Zeeman term on the de Haas van Alphen (dHvA) oscillation in two-dimensional two-band systems. Both systems with and without the magnetic breakdown are investigated. We found that the Fourier transform amplitudes of the oscillations are not described by the spin reduction factor as in the Lifshitz-Kosevich formalism in two-dimensional systems. The anomalous dependence of the Fourier transform amplitudes on the effective g-factor can be observed by tilting-angle dependence of the dHvA oscillation in Sr2RuO4 and quasi-two-dimensional organic conductors.
