Magnetization Dynamics of a Suspension of Noninteracting Magnetic Particles in the Presence of a Static Uniform Magnetic Field

A theoretical study was made of the increase in the magnetization of a suspension of noninteracting magnetic particles with time after switching on an external constant uniform magnetic field. It was found that the characteristic relaxation time of the process is the same at the initial stage and at the final stage of reaching the equilibrium value of the magnetization and has a minimum in the region of intermediate times.
