Optical properties of pyrochlore oxide
P. Zheng, N. L. Wang, J. L. Luo +2
We present optical conductivity spectra for single crystal at different temperatures. Among reported pyrochlore ruthenates, this compound exhibits metallic be…
Scaling of the anomalous Hall effect in SrCaRuO
R. Mathieu, A. Asamitsu, H. Yamada +5
The anomalous Hall effect (AHE) of ferromagnetic thin films of SrCaRuO (0 0.4) is studied as a function of and temperature . As increases…
Annealing-Dependent Magnetic Depth Profile in Ga[1-x]Mn[x]As
B. J. Kirby, J. A. Borchers, J. J. Rhyne +7
We have studied the depth-dependent magnetic and structural properties of as-grown and optimally annealed Ga[1-x]Mn[x]As films using polarized neutron reflectometry. In addition to…
Influence of defects on the lattice constant of GaMnAs
J. Sadowski, J. Z. Domagala
We study the influence of main compensating defects: As antisites and Mn interstitials, known to occur in GaMnAs ferromagnetic semiconductor, on its structural properties. Our expe…
External control of the direction of magnetization in ferromagnetic InMnAs/GaSb heterostructures
X. Liu, W. L. Lim, L. V. Titova +10
In this paper, we demonstrate external control over the magnetization direction in ferromagnetic (FM) In_{1-x}Mn_{x}As/GaSb heterostructures. FM ordering with T_C as high as 50 K i…
Half-metallic ferromagnetism and structural stability of zincblende phases of the transition-metal chalcogenides
Wen-Hui Xie, Ya-Qiong Xu, Bang-Gui Liu +1
An accurate density-functional method is used to study systematically half-metallic ferromagnetism and stability of zincblende phases of 3d-transition-metal chalcogenides. The zinc…
