GIANT MAGNETO-OPTICAL TRANSITION FOR Pt SUBSTITUTED MnSb FILMS WITH NiAs STRUCTURE

Magneto-optical Kerr rotation spectra in ordered and disordered phases of Fe-Pt alloy films

The magneto-optical Kerr rotation (0,) spectra and the related properties have been measured in ordered and disordered phases of several kinds of Fe-R alloy films. The / 0, 1 in as-deposited (disordered) films becomes gradually larger with increasing Fe content until about SO at% Fe, but the shape of 0 k spectra does not change so much. After annealing, however, all the 0, spectra were changed....

Magneto-Optical Properties of Pr, Ni- and Ce, Ni-Substituted YIG Epitaxial Films Prepared by Sputtering

Films of Y,R,(Fe, Ni),O,, @=PI, Ce) have been epitaxially grown in situ on G&G%O,, ( 1 1 1 ) substrates by rf sputtering. Faraday rotation of Ce, Ni:YIG film decreased with valence change of Ce ions from 3+ to 4+ induced by Ni substitution. On the other hand, PI, Ni:YIG films showed negative Faraday rotation in the visible which slightly increases in negative sign for Ni substitution. Magneto-o...

Novel (Pt/Co/Pt/Ni) multilayers for magneto-optical recording media

The sputter deposited ~Pt/Co/Pt/Ni! multilayer films were studied as possible alternative low Curie temperature multilayers for magneto-optical recording. The Curie temperatures of these multilayers were found to be between 150 and 300 °C, which are much lower than those of Co/Pt multilayers or ~Co,Ni!/Pt multilayers. The coercivities of these multilayers were between 450 and 800 Oe. The Kerr s...

Giant magneto-optical Raman effect in a layered transition metal compound.

We report a dramatic change in the intensity of a Raman mode with applied magnetic field, displaying a gigantic magneto-optical effect. Using the nonmagnetic layered material MoS2 as a prototype system, we demonstrate that the application of a magnetic field perpendicular to the layers produces a dramatic change in intensity for the out-of-plane vibrations of S atoms, but no change for the in-p...
