Numerical Study of Competing Spin-Glass and Ferromagnetic Order
Two and three dimensional random Ising models with a Gaussian distribution of couplings with variance J and non-vanishing mean value J0 are studied using the zero-temperature domain-wall renormalization group (DWRG). The DWRG trajectories in the (J0, J) plane after rescaling can be collapsed on two curves: one for J0/J > rc and other for J0/J < rc. In the first case the DWRG flows are toward th...
متن کاملThe ferromagnetic to spin glass transition
2014 From magnetoresistance measurements in PtFe and PdCo alloys we show that disalignment within the ferromagnetic state begins at concentrations well above a critical concentration at which spin glass order sets in. In PtFe the ferromagnetic to spin glass transition is second order. J. Physique LETTRES 42 (1981) L-17 L-20 ler JANVIER 1981, 9 Classification Physics Abstracts 72.15G 75.30K 2.15...
متن کاملFerromagnetic and spin-glass properties of single-crystalline U2NiSi3
A single crystal of U2NiSi3 was investigated by means of magnetization, electrical resistivity and heat capacity measurements. Whereas the DC magnetic data clearly manifest strongly anisotropic ferromagnetism, the AC magnetic susceptibility data are consistent with spin-glass behaviour, reported previously for polycrystalline samples. Moreover, no distinct anomalies around TC occur in the speci...
متن کامل3d Spin Glass and 2d Ferromagnetic Xy Model: a Comparison
We compare the probability distributions and Binder cumulants of the overlap in the 3D Ising spin glass with those of the magnetization in the ferromagnetic 2D XY model. We analyze similarities and diierences. Evidence for the existence of a phase transition in the spin glass model is obtained thanks to the crossing of the Binder cumulant. We show that the behavior of the XY model is fully comp...
متن کاملNumerical Simulations of Spin Glass Systems
We discuss the status of Monte Carlo simulations of (mainly finite dimensional) spin glass systems. After a short historical note and a brief theoretical introduction we start by discussing the (crucial) 3D case: the warm phase, the critical point and the cold phase, the ultrametric structure and the out of equilibrium dynamics. With the same style we discuss the cases of 4D and 2D. In a few ap...
