Abstract

We explore the behavior of the nearest-neighbor Ising spin glass with discrete bonds (± J) on the face-centered cubic lattice using both Monte Carlo simulations and high-temperatureexpansions. A phase transition to a spin glass phase is found in zero magnetic field(H)at a nonzerotemperature(T - Tc), with critical exponents close to that for the simple cubic lattice. In the(H, T)-plane, the contours of constant spin glass susceptibility show an upturn towards higherHatthe lowestT, consistent with the possibility of a de Ahneida-Thouless line of phase transitions in afield. Further, the upturn is similar to those on the simple cubic lattice and less pronounced than onthe four-dimensional hypercubic lattice, despite the higher coordination number of the f.c.c. lattice, suggesting that the upturn is a dimension-related property.
