Relaxation time of magnetization for superparamagnetic particles with uniaxial symmetry

الملخص EN

-In this paper, tve present an analytical formulation of the relaxation time r of magnetization for superpuramagnetic particles, using the theory of brownien motion.

We use a mathematical method to solve the Fokker-Planck equation derived by Brown.

It describes the evolution of the probability density, in the absence and presence of an external magnetic field.
