Abstract
It is shown that depending on how one analyzes measurements of the temperature dependence of magnetization near the Curie temperature it is possible to conclude that the critical exponent changes near Tc. An apparent change in β can be obtained from analyzing data generated from an equation of state in which β does not change. The mathematical and experimental difficulties in the use of the kink‐point locus method are discussed.This publication has 6 references indexed in Scilit:
