AC Magnetostriction Biased on DC Magnetization in Various Magnetization Directions.

AC-driven quantum spins: resonant enhancement of transverse DC magnetization

Magnetic resonance effects have been long studied and used for various spectroscopic methods1–3. Timedependent external fields being an integral part of the physical setups, become also very interesting in their action when entering the field of spintronics and processing of quantum information. While the linear response of a system (probe) to external fields may be typically understood in a ra...

Magnetization and Magnetostriction of Terbium-scandium Alloys

Lattice parameters, magnetization, thermal expansion and magnetostriction of a series of single crystal and polycrystalline specimens of Tb-Sc alloys have been measured. The various experimental observations are examined in terms of the single ion theory of Callen & Callen and the magnetoelastic energy evaluated for the various compositions.

The hysteretic event in the computation of magnetization and magnetostriction

Magnetization of polydisperse colloidal ferrofluids: effect of magnetostriction.

We exploit magnetostriction in polydisperse ferrofluids in order to generate nonlinear responses and apply a thermodynamical method to derive the desired nonlinear magnetic susceptibility. For an ideal gas, this method has been demonstrated to be in excellent agreement with a statistical method. In the presence of a sinusoidal ac magnetic field, the magnetization of the polydisperse ferrofluid ...

Asymmetric magnetization reversal in exchange biased polycrystalline F/AF bilayers

This paper describes a model for magnetization reversal in polycrystalline Ferromagnetic/Antiferromagnetic exchange biased bilayers. We assume that the exchange energy can be expanded into cosine power series. We show that it is possible to fit experimental asymmetric shape of hysteresis loops in exchange biased bilayer for any direction of the applied field. The hysteresis asymmetry is discuss...
