An Interesting Magnetoresistive System: Sr2FeMoO6
Sugata Ray, D. D. Sarma
Ordered double perovskite oxides of the general formula, A2BB'O6, have been known for several decades to have interesting electronic and magnetic properties. However, a recent repo…
Direct observation of electronic domains in manganites by spatially resolved spectroscopy
D. D. Sarma, Dinesh Topwal, U. Manju +8
We use a spatially resolved, direct spectroscopic probe for electronic structure with an additional sensitivity to chemical compositions to investigate high-quality single crystal…
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…
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…
Novel aspects and strong correlation in the electronic structure of SrFeMoO
Sugata Ray, Priya Mahadevan, Ashwani Kumar +5
We investigate the electronic structure of SrFeMoO combining photoemission spectroscopy with a wide range of photon energies and electronic structure calculations based on…
