Abstract
Spectacularly angle-dependent quantum-oscillations whose frequencies are the combinations of the fundamental frequencies of the individual bands are predicted to be observed in quasi two-dimensional (Q2D) multiband electronic Fermi liquids, such as Sr 2 RuO 4 , owing to the chemical potential oscillation (CPO) and Yamaji effect. Both the high two-dimensionality and weak three-dimensionality of the Q2D system are essential for the angle-dependent phenomena. The temperature dependence of the combination frequency components due to the CPO is found to be differ from that due to the magnetic interaction.
