DYNAMIC BEHAVIOR OF A SUSPENSION OF SUPERCONDUCTING PARTICLES IN AN ALTERNATING MAGNETIC-FIELD

We study the behaviour of a dilute suspension of single crystal high-T(c) superconducting particles in an alternating magnetic field H(e) = H0 cos omega-tau of intermediate amplitude value H0. For the case of the inertia term being neglected and field frequency omega < 1 MHz the analytical solution of the nonlinear equation of rotational motion has been obtained. It is shown that particles rotation theta (tau) is squeezed in one of the zones ((tau/2)n, (tau/2)(n + 1)), n = 0, +/- 1,....theta (tau) and magnetization M(tau) are step-like functions of time.
