Ferromagnetism in cobalt doped n-GaN
S. Dhara, B. Sundaravel, K. G. M. Nair +5
Ferromagnetic ordering is reported in the post-annealed samples of Co doped n-GaN formed by Co+ implantation. A maximum Curie temperature ~ 250K is recorded for the sample with 8 a…
Evolution in the split-peak structure across the Peak Effect region in single crystals of -NbSe
A. D. Thakur, T. V. Chandrasekhar Rao, S. Uji +4
We have explored the presence of a two-peak feature spanning the peak effect (PE) region in the ac susceptibility data and the magnetization hysteresis measurements over a wide fie…
Spin Susceptibility and Superexchange Interaction in the Antiferromagnet CuO
T. Shimizu, T. Matsumoto, A. Goto +3
Evidence for the quasi one-dimensional (1D) antiferromagnetism of CuO is presented in a framework of Heisenberg model. We have obtained an experimental absolute value of the parama…
Disordered Type-II Superconductors: A Universal Phase Diagram for Low-T Systems
S. S. Banerjee, A. K. Grover, M. J. Higgins +9
A universal phase diagram for weakly pinned low-T type-II superconductors is revisited and extended with new proposals. The low-temperature ``Bragg glass'' phase is argued to t…
