Fingerprinting Hysteresis
Helmut G. Katzgraber, Gary Friedman, G. T. Zimanyi
We test the predictive power of first-oder reversal curve (FORC) diagrams using simulations of random magnets. In particular, we compute a histogram of the switching fields of the…
Reversal-field memory in magnetic hysteresis
H. G. Katzgraber, F. Pazmandi, C. R. Pike +4
We report results demonstrating a singularity in the hysteresis of magnetic materials, the reversal-field memory effect. This effect creates a nonanalyticity in the magnetization c…
Metastability and Transient Effects in Vortex Matter Near a Decoupling Transition
C. J. Olson, C. Reichhardt, R. T. Scalettar +2
We examine metastable and transient effects both above and below the first-order decoupling line in a 3D simulation of magnetically interacting pancake vortices. We observe pronoun…
Dynamic transition in driven vortices across the peak effect in superconductors
Mahesh Chandran, R. T. Scalettar, G. T. Zimanyi
We study the zero-temperature dynamic transition from the disordered flow to an ordered flow state in driven vortices in type-II superconductors. The transition current is…
