摘要： A process is provided for modifying the magnetic properties of an intermetallic compound comprising at least iron, or a combination of iron with at least one transition metal, and at least one rare earth element. The process comprises heating the intermetallic compound in a reaction gas containing at least one element of groups IIIA, IVA or VIA of the Periodic Table in the gaseous phase to interstitially incorporate the element or elements of these groups into the crystal lattice of the intermetallic compound. Novel magnetic materials showing easy uniaxial anisotropy, increased spontaneous magnetization and Curie temperatures are produced by the process.

摘要： A method and apparatus for thermal analysis of a solid or liquid sample which evolves or absorbs gas on heating or cooling, wherein the sample is heated or cooled in an enclosed space, the temperature of the sample and the pressure of the gas are continuously monitored by temperature and pressure sensors respectively, and measurements of sample temperature and gas pressure are input to a data processor which also controls the temperature change of the sample. The value of gas pressure as a function of sample temperature and the rate of change of this value with respect to sample temperature are calculated; these functions are characteristic of the sample or of a component of the sample under analysis.
