Current-Driven Resonances in Magnetic Multilayers

Physical Review Letters, 2002
We describe complex variations in resistance of a Co/Cu multilayer, generated by injection of an adjustable dc current density ( approximately 10(9) A/cm(2)) via a point contact. We attribute these variations to coupling of current-induced spin waves to lattice vibrations, leading especially to current-driven resonant excitations of phonons. We propose

Competing Exchange Interactions in Magnetic Multilayers

Physical Review Letters, 2006
We have studied alloying of the nonmagnetic spacer layer with a magnetic material as a method of tuning the interlayer coupling in magnetic multilayers. We have specifically studied the Fe/V(100) system by alloying the spacer V with various amounts of Fe.

Magnetic superlattices and multilayers

Journal of Magnetism and Magnetic Materials, 1999
We briefly review the active areas of current research in magnetic superlattices, emphasizing later years. With recent widening use of advanced technologies, more emphasis has been made on quantitative atomic level chemical and structural characterization.

Micromagnetics of Magnetic Multilayers

Materials Science Forum, 1998
A new micromagnetic approach for multilayered films for magneto-optic (MO) recording has been developed. The model takes into account both the magnetization distribution from layer to layer along the film normal and the splitting into domains. This model is a generalization of the domain growth model, developed for amorphous films of ferrimagnetic ...

Magnetism and magnetoresistance in magnetic multilayers

Solid State Communications, 1997
Abstract The discovery of “giant” magnetoresistance (GMR) has greatly stimulated the study of arrays of thin magnetic films. This informal review tries to describe recent discoveries and puzzles in the magnetic and transport properties of metallic arrays of ferromagnetic films.

Magnetic anisotropy in multilayers

Hyperfine Interactions, 2000
Magnetic anisotropy between in-plane and out of plane magnetic alignments is studied in a variety of multilayer systems using Mossbauer spectrosopy to observe the (Fe) magnetic orientation. The surface anisotropy in Fe/Au (1 1 1) multilayers is measured as K s = 0.9 × 10−3 Jm−2.

Electrodeposited Magnetic Multilayers

MRS Proceedings, 1996
ABSTRACTElectrodeposited magnetic multilayer films consisting of alternating layers of a ferromagnetic and a non-magnetic metal may exhibit giant magnetoresistance (GMR), but the effect is very sensitive to whether deposition is carried out under potentiostatic or galvanostatic control, and the choice of substrate.

Magnetic anisotropy of multilayers

Journal of Magnetism and Magnetic Materials, 1991
Abstract The effect of growth conditions on the magnetic anisotropy of Co/Pd multilayers was studied. Epitaxial [111] multilayers grown at elevated substrate temperature show perpendicular magnetization up to 16 A Co layer thickness, due to a large interface anisotropy K s . The results indicate that K s is mainly of the Neel-type.

Multilayered magnetic materials

Endeavour, 1993
Abstract The deposition of thin films is long established, but the recent development of highly sophisticated techniques has made it possible to build up layered films, at the nanometre level, to very strict specifications. In such layers materials exhibit properties quite different from those displayed in bulk.

Soft magnetic multilayers

Reports on Progress in Physics, 1992
Soft magnetic multilayers are new materials that have been developed for record/play-back heads used in video recorders. For this application a combination of a high saturation magnetization and a high magnetic permeability in the MHz range is required.
