Critical Hysteresis

چکیده

Hysteresis is observed at second order phase transitions. Universal scaling for-mulae for the areas of hysteresis loops are written down. Critical exponents are defined, and related to other exponents for static and dynamic critical phenomena. These relations are verified with Langevin dynamics in both the critical and tricriti-cal mean-field models. A finite-size scaling relation is tested in the two-dimensional Ising model with heat-bath dynamics.

Comment on “ Critical current density from magnetization hysteresis data using the critical - state model ”

A recent paper [Physical Review B 64 014508 (2001)] claims to present an exact method to extract the critical current density J C from the M-H hysteresis curve. We show that this claim appears unjustified.

Disorder-induced critical phenomena in hysteresis: Numerical scaling in three and higher dimensions

We present numerical simulations of avalanches and critical phenomena associated with hysteresis loops, modeled using the zero-temperature random-field Ising model. We study the transition between smooth hysteresis loops and loops with a sharp jump in the magnetization, as the disorder in our model is decreased. In a large region near the critical point, we find scaling and critical phenomena, ...

Anomalous magnetic hysteresis in the microwave surface resistance of MgB 2 superconductor

We report experimental results of the field-induced variations of the microwave surface resistance in samples of MgB2, produced by different methods. By sweeping the DC magnetic field at increasing and decreasing values, we have detected a magnetic hysteresis that can be ascribed to the different magnetic induction, due to the critical state of the fluxon lattice. The hysteresis observed in the...

Modeling nonlinearity and hysteresis due to critical-state flux penetration in hard superconductors

The nonlinear surface impedance of a thin superconducting strip carrying a microwave current has been calculated numerically from first principles based upon flux penetration due to a current-induced critical state. The calculations approach analytic results in the appropriate limit. The technique is useful for design of passive superconducting microwave circuits. Keywords— Critical state, Hyst...
