The switching characteristics of 10 nm thick permalloy elements with submicron widths has been studied by Lorentz microscopy. Of particular interest were the changes that occurred when the end-shape of the elements was modified. Gentle curving of the

It has been established previously that thermal switching in high density magnetic media causes a significant time dependence of the coercivity at least for times >10/sup -8/ s. Here, the classical Arrhenius-Neel model assuming coherent rotation is a

Epitaxial FeTaN films (∼1500 A) were grown as a function of nitrogen flow rate on epitaxial Cu(001) buffer layers (∼2000 A) on Si(001) single crystal substrates to investigate the effect of Ta and nitrogen on the magnetocrystalline anisotropy and

Cu epitaxial films were grown on H-terminated Si(110) and Si(111) substrates by magnetron sputtering. The epitaxial orientation of the Cu films and microstructural characteristics were studied by X-ray diffraction, including the conventional θ –2

A remarkable reduction in coercivity Hc was found in sputtered Fe65Co35(=FeCo) films on Cu, NiFe, Ru, Ta/Cu, Ta/NiFe, or Cu/IrMn underlayers. A decrease in Hc from 120 to 7–12 Oe was observed for Cu, NiFe, and Ru underlayers as thin as 2.5 nm but l

A remarkable reduction in the coercivity Hc of sputtered Fe65Co35 films from 9.6 to 0.7 kA/m was observed using a Cu underlayer as thin as 2.5 nm. The FeCo without Cu exhibited a wide distribution of anisotropy fields up to >80 kA/m while the FeCo wi

Uniaxial Co80Pt20 epitaxial films with in-plane anisotropy were prepared by dc sputter deposition using W/Ag templates on H-terminated Si(110) substrates. The epitaxial relationship as a function of the CoPt thickness, studied by electron and X-ray d

In earlier publications it has been shown that the value and direction of the magnetic anisotropy in FeTaN films can be changed by thermal annealing in a dc magnetic field. These films have potential as future write head materials, and this type of i

The magnetic and structural properties of a series of granular Co/CN films prepared by annealing multilayers of Co and CN have been studied. The films contained both hcp and fcc phases, and grain sizes were in the range 18–27 nm. The coercivity var

Current thin film high performance media have very high viscosity and consequently a significant dependence of the remanent coercivity HCR on the measurement time. The fluctuation field Hf is a parameter commonly used to describe thermal effects and
