Abstract
We present a scaling analysis of magnetic resonance data in Eu0.46Sr0.54S for S, X and Q-bands. Conventional scaling of the linewidth leads to very large values of the exponents. An approach, assuming the existence of a critical field, accounts for our data with physical values of the exponents.
