Temperature scaling analysis of the 3D disordered Ising model with power-law correlated defects

Abstract: We consider the three-dimensional site-diluted Ising model with power-law correlated defects and study the critical behavior of the second-moment correlation length and the magnetic susceptibility in the high-temperature phase. By comparing, for various defect correlation strengths, the extracted critical exponents $\nu$ and $\gamma$ with the results of our previous finite-size scaling study, we consolidate the exponent estimates.
