Ordering In A Spin Glass under Applied Magnetic Field

  title={Ordering In A Spin Glass under Applied Magnetic Field},
  author={Dorothee Petit and Luc Fruchter and Ian A. Campbell},
  journal={Physical Review Letters},
Torque, torque relaxation, and magnetization measurements on a AuFe spin glass sample are reported. The experiments carried out up to 7 T show a transverse irreversibility line in the (H,T) plane up to high applied fields, and a distinct strong longitudinal irreversibility line at lower fields. The data demonstrate for that this type of sample, a Heisenberg spin glass with moderately strong anisotropy, the spin glass ordered state survives under high applied fields in contrast to predictions of…

Thermodynamic glass transition in a spin glass without time-reversal symmetry

Evidence is shown for the presence of a phase transition in a four-dimensional spin glass in a field using massive numerical simulations carried out on the Janus special-purpose computer, and a new and powerful finite-size scaling method.

"Glassy Dynamics" in Ising Spin Glasses-Experiment and Simulation-

The field-cooled magnetization (FCM) processes of Ising spin glasses under relatively small fields are investigated by experiment on Fe 0.55 Mn 0.45 TiO 3 and by numerical simulation on the

Replica symmetry breaking transition of the weakly anisotropic Heisenberg spin glass in magnetic fields.

A replica symmetry breaking transition occurs in the chiral sector accompanied by the simultaneous spin-glass order, consistent with the spin-chirality decoupling-recoupling scenario of aspin-glass transition.

Monte Carlo study of the ordering of the weakly anisotropic heisenberg spin glass in magnetic fields

The ordering of the three-dimensional Heisenberg spin glass with the weak random anisotropy in magnetic fields is studied by extensive equilibrium Monte Carlo simulations. Both the spin and the

Heisenberg Spin Glass Experiments and the Chiral Ordering Scenario

An overview is given of experimental data on Heisenberg spin glass materials so as to make detailed comparisons with numerical results on model Heisenberg spin glasses, with particular reference to

Monte Carlo Studies of the Ordering of the Three-Dimensional Isotropic Heisenberg Spin Glass in Magnetic Fields

Spin and chirality orderings of the three-dimensional Heisenberg spin glass under magnetic fields are studied by large-scale equilibrium Monte Carlo simulations. It is found that the chiral-glass

Spin-glass transition of the three-dimensional Heisenberg spin glass.

It is shown, by means of Monte Carlo simulation and finite size scaling analysis, that the Heisenberg spin glass undergoes a finite-temperature phase transition in three dimensions. There is a single

Off-equilibrium fluctuation-dissipation relations in the 3d Ising spin glass in a magnetic field

We study the fluctuation-dissipation relations for a three dimensional Ising spin glass in a magnetic field both in the high temperature phase as well as in the low temperature one. In the region of
