On the origin of magnetoresistance in SrFeMoO
D. D. Sarma, Sugata Ray, K. Tanaka +1
We report detailed magnetization () and magnetoresistance () studies on a series of SrFeMoO samples with independent control on anti-site defect and grain boundary d…
Metal-insulator Crossover Behavior at the Surface of NiS_2
D. D. Sarma, S. R. Krishnakumar, E. Weschke +8
We have performed a detailed high-resolution electron spectroscopic investigation of NiS and related Se-substituted compounds NiSSe, which are known to be gapped in…
Structural and doping effects in the half-metallic double perovskite CrWO
J. B. Philipp, P. Majewski, L. Alff +9
he structural, transport, magnetic and optical properties of the double perovskite CrWO with have been studied. By varying the alkaline earth ion on…
Exploring the high pressure phase diagram of LaCaMnO
A. Sani, C. Meneghini, S. Mobilio +3
The structure of LaCaMnO solid solutions (x=0, 0.25, 0.50, 0.67, 1) under high pressure (up to 40-45 GPa) has been investigated by synchrotron X-ray powder diff…
In situ photoemission study of the room-temperature ferromagnet ZnGeP_2:Mn
Y. Ishida, D. D. Sarma, K. Okazaki +7
The chemical states of the ZnGeP:Mn interface, which shows ferromagnetism above room-temperature, has been studied by photoemission spectroscopy. Mn deposition on the ZnGeP$_…
