Modeling of micromagnetic Barkhausen activity using a stochastic process extension to the theory of hysteresis

Modeling saturated and unsaturated ferroelectric hysteresis loops: An analytical approach

In ferroelectric materials, hysteresis behavior is very difficult to model due to its nonlinear and history-dependent characteristics. Among approaches that are able to describe unsaturated loops, many of them are either very complicated numerical procedures must be employed or the resulting loops contain some undesirable or defective features. In this work, a simple hysteresis model based on a...

Random hysteresis loops

Dynamical hysteresis is a phenomenon which arises in ferromagnetic systems below the critical temperature as a response to adiabatic variations of the external magnetic field. We study the problem in the context of the mean-field Ising model with Glauber dynamics, proving that for frequencies of the magnetic field oscillations of order N−2/3, N the size of the system, the “critical” hysteresis ...

Preparation and Characterization of Electrodeposited Iron + Cobalt Thin Films from a Chloride Bath

Ligas Fe-Co foram depositadas e dissolvidas em solução contendo íons metálicos e em solução de NH 4 Cl. Resultados voltamétricos sugerem interação entre os componentes da liga, originando uma solução sólida. Perfis de ALSV apresentam diferenciação para o processo de dissolução dos metais individuais e das ligas, com comportamento semelhante ao observado para cobalto e/ou ferro, com deslocamento...
