Spin mixing conductance at a well-controlled platinum/yttrium iron garnet interface
Z. Qiu, K. Ando, K. Uchida +6
A platinum (Pt)/yttrium iron garnet (YIG) bilayer system with a well-controlled interface has been developed; spin mixing conductance at the Pt/YIG interface has been studied. Crys…
Origin of the spectral linewidth in non linear oscillators based on MgO tunnel junctions
B. Georges, J. Grollier, V. Cros +6
We demonstrate the strong impact of the oscillator agility on the line broadening by studying spin transfer induced microwave emission in MgO-based tunnel junctions with current. T…
Origin of the anomalous magnetic circular dichroism spectral shape in ferromagnetic (Ga,Mn)As: Impurity bands inside the band gap
K. Ando, H. Saito, K. C. Agarwal +2
The electronic structure of a prototype dilute magnetic semiconductor (DMS), Ga1-xMnxAs, is studied by magnetic circular dichroism (MCD) spectroscopy. We prove that the optical tra…
Local electronic structure of Cr in the II-VI diluted ferromagnetic semiconductor ZnCrTe
M. Kobayashi, Y. Ishida, J. I. Hwang +16
The electronic structure of the Cr ions in the diluted ferromagnetic semiconductor ZnCrTe ( and 0.15) thin films has been investigated using x-ray magnetic circ…
Enhancement of the spin pumping efficiency by spin-wave mode selection
C. W. Sandweg, Y. Kajiwara, K. Ando +2
The spin pumping efficiency of lateral standing spin wave modes in a rectangular YIG/Pt sample has been investigated by means of the inverse spin-Hall effect (ISHE). The standing s…
Magneto-optical study of ZnO based diluted magnetic semiconductors
K. Ando
Magneto-optical properties of ZnO:Co and ZnO:Ni films were measured. Magnetization measurements show that some of the films are paramagnetic and others are ferromagnetic. Magnetic…
