Ferromagnet in a continuously tuneable random field
D. M. Silevitch, D. Bitko, J. Brooke +3
The Random-Field Ising Model (RFIM) has been extensively studied as a model system for understanding the effects of disorder in magnets. Since the late 1970s, there has been a part…
Tunable Quantum Tunneling of Magnetic Domain Walls
J. Brooke, T. F. Rosenbaum, G. Aeppli
Magnetic domain wall tunneling is observed in the disordered Ising ferromagnet LiHo_{0.44}Y_{0.56}F_4. The tunneling can be tuned by applying a magnetic field transverse to the Isi…
Quantum Annealing of a Disordered Magnet
J. Brooke, D. Bitko, T. F. Rosenbaum +1
Traditional simulated annealing utilizes thermal fluctuations for convergence in optimization problems. Quantum tunneling provides a different mechanism for moving between states,…
History Dependent Phenomena in the Transverse Ising Ferroglass: the Free Energy Landscape
Ying-Jer Kao, G. S. Grest, K. Levin +3
In this paper we investigate the relationship between glassy and ferromagnetic phases in disordered Ising ferromagnets in the presence of transverse magnetic fields, . Iterative…
