The Atomic Moments and Hyperfine Fields in Fe2Ti and Fe2Zr
The magnetic properties of Fe2Ti and Fe2Zr, intermetallic compounds with Laves type structures, were studied using the techniques of neutron diffraction and nuclear resonance fluorescence (Mössbauer effect). Both compounds are ferromagnetic, with magnetic moments of 0.35 and 2.56 Bohr magnetons, respectively, at room temperature, and 0.92 and 3.12 Bohr magnetons, respectively, at liquid helium temperatures. A magnetic form factor for the iron atoms in Fe2Zr was determined. The nuclear resonance fluorescence experiments gave measures of the magnetic fields at the iron nuclei. At room temperature, the field for Fe2Zr was 190±10 kgauss, while that for Fe2Ti was very low, less than 5 kgauss. The relation between the atomic magnetic moments and the magnetic fields at the nuclei is discussed.
