Magnetization of lutetium iron garnet near the critical point

A study has been made of the critical magnetic properties of lutetium iron garnet. Values of the critical exponents, β, δ and λ were seen to fulfill the scaling relation, β(δ?1)=λ, within the limits of experimental error. The critical temperature, obtained from the kink-point plot of applied magnetic field vs break-point temperature, was reaffirmed through utilization of the Kouvel-Fisher analysis.
