Nuclear orientation of⁴⁸V in Fe and Co and NMR of⁴⁸VFe

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 ...

Nuclear resonance studies of⁹⁵NbFe

Dilute alloys of 35-day⁹⁵Nb in polycrystalline iron have been studied by nuclear magnetic resonance on oriented nuclei (NMR/ON) using frequency modulation and fast passage techniques. Comparison of resonance freq...

Nuclear orientation of⁶⁰Co in concentrated CoAu alloys

We report β-particle and γ-ray angular distribution measurements from⁶⁰Co oriented in CoAu at low temperatures in applied fields up to 72 kOe and Co concentrations of 0.95 to 11 at.%. The results are explained by...

NMR detected by Mössbauer-effect, applied to the system⁵⁷CoFe

The detection of NMR in oriented nuclei via the Mößbauer effect in the daughter state is described and its specific advantages and drawbacks compared to other methods. As an example, the NMR of⁵⁷Co in Fe was obse...

Critical field for superconductivity and low-temperature normal-state heat capacity of tungsten

We have measured the critical magnetic field for superconductivity in tungsten from 5.5 to 15 mK using a γ-ray anisotropy thermometer, and we have measured the heat capacity between 0.35 and 25 K. Analysis of ...

Search for superconductivity in lithium and magnesium

Recent theoretical work suggests that magnesium and lithium should be superconducting in the m°K temperature range. We have cooled samples of each of these metals to a temperature of 4 m°K, measured by a gamma...
