The nonlinear dielectric relaxation of an assembly of polar molecules submitted to the action of a dc field superimposed on an ac electric field is studied theoretically in the framework of the noninertial rotational diffusion model. It is also assum

Nonlinear response of a uniaxially anisotropic superparamagnetic particle subjected to a dc bias and strong ac field is evaluated. For the third harmonic, a non-monotonic dependence of the response amplitude on the strength of the oscillating field (

The dielectric relaxation of molecular impurities in cubic crystals is treated by averaging the Langevin equation for noninertial rotational Brownian motion of a linear rotator in a cubic potential, so that the system of linear differential-recurrenc

The problem of the nonlinear transient response of a system of rigid dipolar particles (macromolecules) diluted in a nonpolar solvent to a sudden change of an external dc field both in magnitude and direction is considered. On solving the noninertial

Magnetic relaxation in Ni nanowires was measured both on single nanowires and on an array of about 106 nanowires. The logarithmic relaxation rate S = dM/d ln(t) deduced from after-effect experiments is presented as a function of both the applied fiel
