The effects of the precursor milling energy on the superconducting and microstructural homogeneity of Fe-sheathed MgB2 monocore wires and tapes have been investigated. The conductors were produced by the powder-in-tube method using drawing and rolling deformation methods and in situ reaction. Combined magnetooptical, structural and magnetization measurements were performed on MgB2 superconducti...

The results of experimental investigation of longitudinal hysteresis of epitaxial garnet films with "easy axis in plane" anisotropy using magnetooptical method are presented. The orientational phase transition isolines corresponding to change in magnetic reversal mechanisms at room (T=293 K) and near liquid nitrogen (T=90 K) temperatures are obtained by visual observation along easy axis of mag...

Lanthanide metals are a particular class of magnetic materials in which the magnetic moments are carried mainly by the localized electrons of the 4f shell. They are frequently found in technically relevant systems, to achieve, e.g., high magnetic anisotropy. Magnetooptical methods in the x-ray range are well suited to study complex magnetic materials in an element-specific way. In this work, we...

In a magnetic amplifying magnetooptical system (MAMMOS) disk, the copying process of a magnetic domain from the recording layer into the readout layer is investigated by using a laser spot diameter of 0.66 m. Interference between neighboring bits occurs when the spatial resolution of the copy process is larger than half the domain size. It is observed that a reduction of the readout power from ...

AbsrraclSeveral series of sputtered Co/Ni multilayer thin films have been investigated. The volume and interface contributions to the magnetic anisotropy were determined from magnetization measurements, and the interface anisotropy, 6 = 0.23 f 0.03 erg/cm2, was found to support perpendicular magnetic anisotropy. The anisotropy constant, K, increased with the Au buffer layer thickness, indicatin...
