摘要

考虑具有幂律相关缺陷的三维位置稀释Ising模型，研究了高温相中二阶矩相关长度和磁化率的临界行为。通过比较，对于各种缺陷相关强度，提取的临界指数ν和γ与我们之前的有限尺寸缩放研究结果，我们巩固了指数估计。

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

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 ν and γ with the results of our previous finite-size scaling study, we consolidate the exponent estimates.
