We study the influence of vacancy concentration on the behaviour of the three dimensional Random Field Ising model with metastable dynamics. We focus our analysis on the number of spanning avalanches which allows for a clean determination of the critical line where the hysteresis loops change from continuous to discontinuous. By a detailed finite size scaling analysis we determine the phase diagram and prove numerically the critical exponents along the whole critical line. Finally we discuss… Expand

A study of Barkhausen avalanche statistics through the critical disorder in a ferromagnetic thin film: Experimental investigation and theoretical modeling
Abstract It is well known from theoretical models that a ferromagnetic system should undergo a disorder induced phase transition in its magnetization reversal mode at a critical disorder level R C ,Expand

We report the crossover of Barkhausen noise statistics upon a change in the measurement geometry. The behaviour is akin to the angle dependent critical to sub-critical crossover of avalancheExpand
Spreadsheet analysis of stability and meta-stability of low-dimensional magnetic particles using the Ising approach
Modelling hysteresis behaviour, as it can be found in a broad variety of dynamical systems, can be performed in different ways. An elementary approach, applied for a set of elementary cells, whichExpand
