摘要：

TbFeCo alloys have important applications in rewritable optical recording media. In order to determine the contributions to the magneto-optic activity from the rare-earth and transition-metal constituents, we have measured the temperature dependence of the magnetization, Kerr rotation, and Kerr ellipticity. The standard mean field method is shown to be inadequate for this analysis. We introduce a ratio method which provides quick, rough measurements of the contributions to the magneto-optic activity from the alloy constituents.
