摘要
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-temperature expansions. A phase transition to a spin glass phase is found in zero magnetic field (H) at a nonzero temperature (T = T(c)), 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 higher H at the lowest T, consistent with the possibility of a de Almeida-Thouless line of phase transitions in a field. Further, the upturn is similar to those on the simple cubic lattice and less pronounced than on the four-dimensional hypercubic lattice, despite the higher coordination number of the fc.c. lattice, suggesting that the upturn is a dimension-related property.
