The property of multilayered SmCo5 film with perpendicular magnetic anisotropy

PHYSICA STATUS SOLIDI (A) APPLICATIONS AND MATERIALS SCIENCE, Issue 12 2007
Shigeto Takei
Abstract In order to fabricate thick SmCo5 film, the dependences of the magnetic properties of SmCo/Ru/Cu/Ru films and its multilayer films on the SmCo layer thickness were studied. The SmCo/Ru/Cu/Ru film with the SmCo layer thickness up to 200 nm showed the perpendicular magnetic anisotropy while the multilayer film with the total SmCo layer thickness of 1000 nm indicated the magnetic easy axis was in the perpendicular direction. It was found that the multilayered structure is preferable for the increase in total thickness of the SmCo layer with the perpendicular anisotropy. (© 2008 WILEY-VCH Verlag GmbH & Co.

Growth of epitaxial garnet film by LPE for application to integrated magneto-optic light switch arrays

PHYSICA STATUS SOLIDI (A) APPLICATIONS AND MATERIALS SCIENCE, Issue 8 2004
J. H. Park
Abstract We investigate the dependence of the properties of garnet films grown by liquid phase epitaxy (LPE) on the procedure and the temperature of growth to tailor magnetic properties of Bi, Gd, Ga:YIG film for application to integrated magneto-optic light switch arrays. Because the yttrium and gallium concentrations of the films decreased slightly and the bismuth, iron concentrations of the films increased slightly with decreases of the growth temperature, the magnetic properties of the garnet film grown by LPE are very sensitive specially to a growth temperature. The decrease of Hsat with decreasing growth temperature indicates that the perpendicular magnetic anisotropy energy of the film decreases. The Bi, Gd, Ga:YIG film grown at around 730 °C have good magnetic properties, i.e., a low value of 4,Ms of 120 G, a low value of saturation field Hsat of 168 Oe, and a low perpendicular magnetic anisotropy for application of the magneto-optic spatial light modulators.

Depinning field from notches on Co/Pd multilayer nanowires with perpendicular magnetic anisotropy

PHYSICA STATUS SOLIDI (C) - CURRENT TOPICS IN SOLID STATE PHYSICS, Issue 12 2007
Sug-Bong Choe
Abstract Domain-wall pinning and depinning mechanisms of ferromagnetc nanowires with perpendicular magnetic anisotropy were investigated. Micromagnetic simulation results revealed that the depinning field from notches were determined solely by the gap distance between the notches, irrespective to the wire width and the notch size. The double-notch wires exhibited two-fold décalcomanie domain patterns and one half patterns were identical to those of single-notch wires. Therefore, the double-notch wires showed the same depinning field compared to single-notch wires with half width. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim) [source]
