We have carried out an exploratory NMR study of interdiffusion at interfaces between epitaxially grown laminae of rare-earth metals. The system investigated was a terbium - yttrium superlattice grown by molecular-beam epitaxy at . The NMR spectrum of

We have made an NMR study of the effect of yttrium substitution on the hyperfine splitting of in ferromagnetic terbium at 4.2 K. In conventionally prepared polycrystalline samples the average transferred hyperfine field increases linearly with yttriu

We have studied the zero-field hyperfine splitting of in ferrimagnetic (x = 1, 1.5, 2) using spin-echo NMR at 4.2 K. Distinct spectra arising from the different sites characterized by the numbers of carbon nearest neighbours (NN = 0, 1, 2, 3) are obs

We have measured the hyperfine fields of in and compounds using spin-echo NMR at 4.2 K. The results, together with complementary data obtained from other sources, are interpreted in terms of a simple model which involves hyperfine fields transferred

We have studied the field dependence of the hyperfine splitting of 165Ho in yttrium hydroxide by spin echo NMR at liquid helium temperatures and in fields up to 8 T. Hyperfine spectra have been obtained from the electronic ground state and from the f

We have studied the field dependence of the hyperfine splitting of holmium as a dilute substituent in a lamina of dysprosium prepared by molecular-beam epitaxy. The measurements were made by spin-echo NMR at temperatures below 2 K and in fields up to

The zero-field hyperfine splitting of 159Tb in ferrimagnetic Tb2Co17 has been studied by NMR at 4.2 K. Distinct domain and wall spectra are obtained from the dominant rhombohedral phase; weaker spectra from the two inequivalent lanthanide sites in th

Two high galactic latitude B-type stars, PHL 1580 and PHL 174, originally identified as distant early-type objects from low-resolution spectroscopy and photometry are re-analysed using high-resolution spectra. The results of LTE and non-LTE model atm
