Physics of Superconductivity and Magnetism

The magnetic-breakdown (MB) phenomena in the magnetization oscillation in metals are investigated theoretically in order to explain the interference difference oscillation observed in low-dimensional organic conductors, which is prohibited in the often used network model of semiclassical theory for MB. Our full quantum-mechanical theory reproduces various oscillations, including the interference difference oscillation and demonstrates a smooth crossover to the MB orbit oscillation, or MB phenomenon. This is interpreted in terms of the recursive band structures. We point out some pitfalls when analyzing experiments in higher fields.
