Ginzburg--Landau Vortices: Dynamics, Pinning, and Hysteresis [PDF]
SIAM Journal on Mathematical Analysis, 1997 There are considered three problems related to the mathematical theory of vortex phenomena in superconductivity based on the Ginzburg-Landau models. First, it is studied the long-time behaviour of solutions to the time dependent Ginzburg-Landau equations.

Properties of dynamic magnetic loss of ferrite
AIP Advances, 2018 The B-H loop of ferrite becomes narrower with a decrease in the excitation frequency. However, even at frequencies lower than 1 kHz, the B-H loop exhibits a certain minimum width, which is referred to as the (DC) hysteresis loop, and its area corresponds
