Abstract
The problem of probe disturbance is considered for static critical exponents that are determined from hyperfine fields on isolated impurity probes in a magnetic solid. Based on Ising model calculations and reanalysis of relevant experimental data, it is concluded that for reduced temperatures restricted tot≤10−2, the systematic error made in a hyperfine measurement of the exponent β is less than 2%.
