Experimental Realization of the 1D Random Field Ising Model
N. S. Bingham, S. Rooke, J. Park +8
We have measured magnetic-field-induced avalanches in a square artificial spin ice array of interacting nanomagnets. Starting from the ground state ordered configuration, we imaged…
Connecting Complex Electronic Pattern Formation to Critical Exponents
Shuo Liu, E. W. Carlson, K. A. Dahmen
Scanning probes reveal complex, inhomogeneous patterns on the surface of many condensed matter systems. In some cases, the patterns form self-similar, fractal geometric clusters. I…
Hysteresis in driven disordered systems: From plastic depinning to magnets
M. Cristina Marchetti, Karin A. Dahmen
We study the dynamics of a viscoelastic medium driven through quenched disorder by expanding about mean field theory in dimensions. The model exhibits a critical point separa…
Hysteresis Loop Critical Exponents in 6-Epsilon Dimensions
Karin Dahmen, James P. Sethna
The hysteresis loop in the zero-temperature random-field Ising model exhibits a critical point as the width of the disorder increases. Above six dimensions, the critical exponents…
