Two-dimensional ferromagnetic systems with finite driving

We study the effect of finite driving by the time-varying external magnetic field in the two-dimensional disordered ferromagnetic systems portrayed on the case of nonequlibrium athermal random field Ising model. The response of studied systems is rate-dependent exhibiting scaling and data collapsing above the dynamical critical point in the full range of driving rates provided that the system parameters satisfy both the finite-size and here introduced rate-dependent scaling conditions. These findings are based on extensive numerical simulations of large systems reliably demonstrating the observed behavior and could be relevant for real thin systems driven at finite rates.(c) 2022 Elsevier Ltd.

Automated summary

This study investigates the effect of finite driving by a time-varying external magnetic field in a two-dimensional disordered ferromagnetic system, using the case of the nonequilibrium athermal random field Ising model. The response of the studied systems is rate-dependent and exhibits scaling and data collapsing above the dynamical critical point, as long as the system parameters satisfy both the finite-size and rate-dependent scaling conditions. These findings are derived from extensive numerical simulations of large systems, providing reliable evidence for the observed behavior, and could be relevant to real thin systems driven at finite rates.
