The nonlinear magnetic $\chi_{3}$ and spin-glass $\chi_{sg}$ susceptibilities in zero applied field are obtained, from tempered Monte Carlo simulations, for three different spin glasses (SGs) of Ising spins with quenched site disorder. We find that t

By tempered Monte Carlo simulations, an Almeida-Thouless (AT) phase-boundary line in site-diluted Ising spin systems is searched for. Spins interact only through dipolar fields and occupy a small fraction of lattice sites. The spin-glass susceptibili

Stamp and Tupitsyn (ST) have recently posted a Comment (P.C.E. Stamp and I.S. Tupitsyn, arXiv:cond-mat/0211413) on a Letter of ours (J.J. Alonso and J.F. Fernandez, Phys. Rev. Lett. v87, 097205 (2001)). They claim that, in our Letter, ``Short-time re

Currently, spin tunneling at very low temperatures is assumed to proceed as an incoherent sequence of events that take place whenever a bias field h(t) that varies randomly with time t becomes sufficiently small, as in Landau-Zener transitions. We st
