The existence of magnetic domains in non-ferromagnetic metals at quantizing magnetic fields is examined under conditions of de Haas-van Alphen oscillations in the range of strong magnetic fields and low temperatures in thin slabs in a three-dimensional electron gas. Dynamics of Condon domain walls are studied in bulk metals and films at time-independent and time-varying applied magnetic fields. Domain wall resonance and relaxation effects are considered. The temperature, magnetic field, impurities and sample size-dependent effects on the width, velocity and mobility of domain walls are calculated. Magnons of a non-spin nature are defined and discussed. It is shown that the magnetic induction splitting in the sample due to the existence of the domain stripe structure changes the distribution of magnetic field in vacuum above the surface of the sample. Detection of these changes by Hall probes can give information about spatial configuration of Condom domain structure.
