Magnetic characterization of exchange-coupled composite media
In this work we compare the magnetization reversal processes in a set of exchange-coupled composite (ECC) media and a similar set of continuous granular coupled (CGC) media. We have studied the revers...

We investigate magnetization reversal and thermal stability (energy barriers) properties of composite media, for a broad range of saturation magnetization values, comparing the case of individual grai...

The DeltaH(M,DeltaM) method and its ability to determine the intrinsic switching field distributions of perpendicular recording media are numerically studied. Strong evidence is presented that this method, which is based on the mean-field approximation, has a well-defined reliability range, corroborating earlier results from micromagnetic and hysteron simulations. Specifically, it is shown that this well-behaved failure appears to be universal and independent from the actual lattice structure. ©2008 American Institute of Physics
