A nuclear orientation study of a single crystal of the β phase of iron–germanium

Abstract

The low-temperature nuclear-orientation technique was applied to two single crystals of Fe1.67Ge, one doped with traces of 54Mn and the other with traces of 60Co, and the magnitudes of the effective hyperfine fields were deduced at these two nuclear sites. An estimate of the spin-lattice relaxation time constant was also found for the MnFe1.67Ge and CoFe1.67Ge systems.
