Ferromagnetic resonance in Mn5Ge3 epitaxial films with weak stripe domain structure

Weak-stripe magnetic domain evolution with an in-plane field in epitaxial FePd thin films: Model versus experimental results

The magnetic domain structure in thin ferromagnetic films with perpendicular anisotropy is investigated. The effect of an in-plane magnetic field on the presence of domains and the magnetization profile is analyzed within the framework of a one-dimensional analytical model. The general results are reported in a state diagram as a function of the two relevant dimensionless parameters: the qualit...

Stripe glasses in ferromagnetic thin films

Spin polarization and electronic structure of ferromagnetic Mn5Ge3 epilayers

Semiconductor spintronics has recently been recognized for its potential to combine the spin selectivity and nonvolatility of ferromagnetic compounds with the ability to fabricate hybrid thin-film devices naturally integrated with conventional semiconductors [1]. Yet in order to succeed in technological applications one has to be able to introduce roomtemperature spin-polarized materials that a...

Domain structure and magnetotransport in epitaxial colossal magnetoresistance thin films

Our studies of compressively strained La0.7Sr0.3MnO7 ~LSMO! thin films reveal the importance of domain structure and strain effects in the magnetization reversal and magnetotransport. Normal and grazing incidence x-ray diffraction indicate that the compressive strain on these LSMO thin films on ~100! LaAlO3 is not completely relaxed up to thicknesses on the order of 1000 Å. The effect of the co...

Magnetic anisotropy of epitaxial MgO/Fe/MgO films studied by network analyzer ferromagnetic resonance

The dynamic magnetic properties of MgO/Fe epitaxial thin films are investigated through a network analyzer ferromagnetic resonance in the 0–26-GHz range. The high-frequency response is measured for applied in-plane magnetic fields comparable to the fourfold magnetocrystalline anisotropy of the film, resulting in large-angle in-plane quasistatic motion of the magnetization. We show that the vari...
