Fast and Slow Magnetization Processes in Magnetic Recording Media
Information loss due to thermal activation is a major concern in ultrahigh-density magnetic recording media. The usually considered mechanism is thermally activated magnetization reversal over micromagnetic energy barriers. However, micromagnetic approaches ignore local anisotropy fluctuations, which translate into a time-dependent reduction of the remanent magnetization. The effect is negligib...

متن کاملIdentification and Inversion of Magnetic Hysteresis for Sinusoidal Magnetization
The sinusoidal magnetization of a sample material is difficult to achieve, since the magnetic hysteresis poses a strong non-linearity. In order to find the proper input voltage, a feed-forward strategy with a hysteresis model identification and inversion is proposed. The classical Preisach model in the Everett formulation is used for this purpose and eddy current effects are also included. A ne...
متن کاملAsymmetric magnetization reversal in exchange-biased hysteresis loops
Polarized neutron reflectometry is used to probe the in-plane projection of the net-magnetization vector M--> of polycrystalline Fe films exchange coupled to twinned (110) MnF (2) or FeF (2) antiferromagnetic (AF) layers. The magnetization reversal mechanism depends upon the orientation of the cooling field with respect to the twinned microstructure of the AF, and whether the applied field is i...
متن کاملMillimicrosecond Magnetization Reversal in Thin Magnetic Films
From ferromagnetic resonance xperiments and from calculations based on the modified Landau-Lifschitz equation, switching times for the coherent rotation of the magnetization in thin, permalloy-type films have been predicted to lie in the range of 1 mi1limicrosecond.l First measurements by D. 0. Smith et a1,2 utilizing a travellingwave oscilloscope with a response time of 2 mpec, indicated swi...
