Magnetic field dependence of magnetization reversal behavior in CoÕPt multilayers

Magnetic field dependence of magnetization reversal in Co/Pt multilayers has been quantitatively investigated. Serial samples of Co/Pt multilayers have been prepared by dc magnetron sputtering under various Ar pressures. Magnetization reversal was monitored by magnetization viscosity measurement and direct domain observation using a magneto-optical microscope system. The wall-motion speed V and...

Engineering magnetic anisotropy and magnetization switching in multilayers by strain.

The effect of the strain on the magnetic properties of metallic multilayers has been investigated by ab initio studies. Our results indicate that the magnetic anisotropy energy (MAE) of an Fe(001) surface can be drastically enhanced by capping with 5d elements. By choosing Ir-Fe multilayers as a model system, we demonstrate that the MAE which depends on the composition and the structure of the ...

Low frequency magnetic response in antiferromagnetically coupled Fe/Cr multilayers.

The magnetic field and temperature dependence of the low frequency magnetic response of antiferromagnetically coupled Fe/Cr(100) multilayers has been studied between +/-500 Oe, from 2 to 300 K. At T = 2 K the losses exhibit an unusually strong frequency dependence which can be described within a single relaxation time scheme. This relaxation time proves to be strongly field dependent. These phe...
