Dynamic scaling in spin glasses
Dynamic scaling in spin glasses
We present neutron spin echo (NSE) results and a revisited analysis of historical data on spin glasses, which reveal a pure power-law time decay of the spin autocorrelation function $s(Q,t)=S(Q,t)/S(Q)$ at the glass temperature ${T}_{g}.$ The power law exponent is in excellent agreement with that calculated from dynamic and static …
