Journal ArticleDOI

Dynamics of the Relaxation-Time Spectrum in a CuMn Spin-Glass

TL;DR: In this article, the authors show that the zero-field-cooled magnetization strongly depends on the time the sample is kept at constant temperature prior to the field application, which is at variance with the common belief that an equilibrium spin-glass state is quickly obtained after cooling in zero field.
Journal ArticleDOI

Dynamics of an Ising spin-glass in the vicinity of the spin-glass temperature.

TL;DR: The functional form of $q(t)$ shows a remarkable agreement with the results obtained from Monte Carlo simulations on a three-dimensional Ising spin-glass, as reflected in low-field ac susceptibility and time-dependent magnetization measurements.
Journal ArticleDOI

Measurement of complex susceptibility on a metallic spin glass with broad relaxation spectrum

TL;DR: In this paper, the in-phase and out-of-phase properties of a spin glass were investigated and it was shown that the properties of spin glass have a broad spectrum of relaxation times.
Journal ArticleDOI

First Order Magnetic Phase Transition in Fe2P

TL;DR: The magnetic properties of stoichiometric Fe2P and non-stochastic Fe2-xP (0 < × ≤ 0.06) have been studied by means of magnetic susceptibility as mentioned in this paper.
Journal ArticleDOI

Static scaling in a short-range Ising spin glass

TL;DR: The results support the existence of a finite-temperature phase transition in a three-dimensional Ising spin glass.
