Abstract
Observations of the anisotropies of the 984 and 1312 keV γ-rays from48VFe and48VCo in fields up to 4 T and temperatures down to 4 mK show extremely long nuclear spin-lattice relaxation times (3–4 h in Fe, 8 h in Co host) and indicate negative hyperfine fields in both hosts. The Fe measurements show a magnetic moment for the48V 4+ ground state considerably larger than previously reported. This is confirmed by NO/NMR of48VFe, giving μ(4+)=2.012(11) μN. The advantages of pulsed NMR techniques, especially in systems with slow relaxation, are discussed.
