Magnetic Phases in a Two Dimensional Antiferromagnet

Abstract

Mossbauer effect experiments in single crystal FeCl3 (anhydrous) show the hyperfine field to vary with temperature according to H(T)=H(o)D(1-T/TN) to the beta power where beta = 0.14 which is indicative of two dimensional magnetic ordering. Further experiments show a spin reorientation for fields of about 40 kiloOersted applied along the c-axis. The boundaries of the magnetic phases in the H-T plane are determined.
