Size-dependent effects on the magnetization dynamics of Condon domains

The existence of magnetic domains in nonferromagnetic metals at quantizing magnetic fields is examined under conditions of de Haas-van Alphen oscillations in the range of strong magnetic fields in thin slabs in a three-dimensional electron gas. Dynamics of Condon domain walls are studied in bulk metals and films at time-varying and time-independent applied magnetic fields. The temperature, magnetic field, purity, and sample size-dependent effects on the width, velocity and mobility of domain walls are calculated. Domain wall resonance and relaxation effects are considered in the three-dimensional electron gas.
