Dynamic critical neutron scattering from a two-Dimensional ising system Rb2CoF4

Abstract

The dynamical behavior of the two-dimensional Ising-like antiferromagnet Rb2CoF4, which is expected to provide a real system within the n=1, d=2, universality class, has been investigated near TN=102.96 K with high-resolution inelastic neutron scattering. Measurement of the characteristic frequency of the longitudinal susceptibility fluctuations yields a dynamic critical exponent z=1.69±0.05. This is close to the conventional theoretical value z==1.75. © 1982 The American Physical Society.
