Comments on the analysis of hyperfine-field distributions in amorphous magnetic solids using a spectrum-subtraction method

Abstract

We show in this Comment that the applicability of the spectrum-subtraction method to analyze the hyperfine-field distribution ${P(H)}$ is limited to a small class of amorphous ferromagnetic alloys. If a small magnetic field does not completely align the magnetic moments in the sample, some of the novel features of the $P(H)$ may be artificially subtracted out before the analysis of $P(H)$ can be made. The differences in the $P(H)$ of METGLAS \textregistered{} 2826-A (${\mathrm{Fe}}_{32}$${\mathrm{Ni}}_{36}$${\mathrm{Cr}}_{14}$${\mathrm{P}}_{12}$${\mathrm{B}}_{6}$) will also be examined.
