Abstract

An analysis is made of the critical‐point behaviour of a 3‐d Ising ferromagnet using a magnetic equation of state based on an expression for the order‐parameter proposed by Frankel. The asymptotic distribution‐function of zeroes for the partition function on a unit‐circle in a complex‐fugacity plane is determined. The critical indices γ and α are found to be 1, and 0 which are inconsistent with high‐temperature series expansion results.
