Modeling exchange bias microscopically
U. Nowak, A. Misra, K. D. Usadel
Exchange bias is a horizontal shift of the hysteresis loop observed for a ferromagnetic layer in contact with an antiferromagnetic layer. Since exchange bias is related to the spin…
Dynamic Transitions in Pure Ising Magnets under Pulsed and Oscillating Fields
Bikas K. Chakrabarti, Arkajyoti Misra
Response of pure Ising systems to time-dependent external magnetic fields, like pulsed and oscillating fields, are discussed and compared here. Because of the two time scales invol…
Mean field and Monte Carlo studies of the magnetization-reversal transition in the Ising model
Arkajyoti Misra, Bikas K Chakrabarti
Detailed mean field and Monte Carlo studies of the dynamic magnetization-reversal transition in the Ising model in its ordered phase under a competing external magnetic field of fi…
Nucleation theory and the phase diagram of the magnetization-reversal transition
Arkajyoti Misra, Bikas K. Chakrabarti
The phase diagram of the dynamic magnetization-reversal transition in pure Ising systems under a pulsed field competing with the existing order can be explained satisfactorily usin…
Length and time scale divergences at the magnetization-reversal transition in the Ising model
R. B. Stinchcombe, A. Misra, B K Chakrabarti
The divergences of both the length and time scales, at the magnetization- reversal transition in Ising model under a pulsed field, have been studied in the linearized limit of the…
Dynamic Magnetization-Reversal Transition in the Ising Model
A. Misra, B. K. Chakrabarti
We report the results of mean field and the Monte Carlo study of the dynamic magnetization-reversal transition in the Ising model, brought about by the application of an external f…
