  "description": "We investigate the dissipative loss in the +/- J Ising spin glass in three dimensions through the scaling of the hysteresis area, for a maximum magnetic field that is equal to the saturation field. We perform a systematic analysis for the whole range of the bond randomness as a function of the sweep rate by means of frustration-preserving hard-spin mean-field theory. Data collapse within the entirety of the spin-glass phase driven adiabatically (i.e., infinitely slow field variation) is found, revealing a power-law scaling of the hysteresis area as a function of the antiferromagnetic bond fraction and the temperature. Two dynamic regimes separated by a threshold frequency omega(c) characterize the dependence on the sweep rate of the oscillating field. For omega < omega(c), the hysteresis area is equal to its value in the adiabatic limit omega = 0, while for omega > omega(c) it increases with the frequency through another randomness-dependent power law.",
