Magnetic phase diagram of the half-filled t-t'-Hubbard model -- finite-U effects on competing interactions and frustration
Avinash Singh
The magnon propagator is evaluated in the AF (π,π,π) and the F-AF (0,π,π) states at the RPA level, and the spin-fluctuation corrections are compared. Transverse spin fluctuations a…
Stability of the doped antiferromagnetic state of the t-t'-Hubbard model
Avinash Singh, Haranath Ghosh
The next-nearest-neighbour hopping term t' is shown to stabilize the AF state of the doped Hubbard model with respect to transverse perturbations in the order- parameter by strongl…
Electromagnetic induction and damping - quantitative experiments using PC interface
Avinash Singh, Y. N. Mohapatra, Satyendra Kumar
A bar magnet, attached to an oscillating system, passes through a coil periodically, generating a series of emf pulses. A novel method is described for the quantitative verificatio…
Spin-dependent electrical transport in ion-beam sputter deposited Fe-Cr multilayers
A. K. Majumdar, A. F. Hebard, Avinash Singh +1
The temperature dependence of the electrical resistivity and magnetoresistance of Xe-ion beam sputtered Fe-Cr multilayers has been investigated. The electrical resistivity between…
