Several alloys close in composition to Nd 2 Fe 14 B and Nd 2 Co 14 B were investigated by standard metallography. It was found that the tetragonal Nd 2 Fe 14 B-type structure applies also to Nd 2 Co 14 B. This structure does not tolerate significant

From a study of the isothermal sections of the Nd-Fe-B phase diagram at 900 °C (neodymium-poor alloys) and 700 °C (neodymium-rich alloys) it was found that the phase Nd2Fe14B has no or at best only a very small homogeneity range. Results of a preli

The construction and performance of a new electron spectrometer for depth-selective conversion electron Mossbauer spectroscopy (DSCEMS) is described, based on a design of a retarding-field analyser. The spectrometer is suited for energies up to 25 ke

The conversion electron Mossbauer spectra of CoFe2−xAlxO4 (x = 0.1, 0.3, 0.6, 0.8 and 1.0) were measured at room temperature. Cation distributions for all samples were derived and compared with the cation distributions as obtained for powdered samp

The magnetic properties of compounds of the R2Fe14B type (R Y, La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er and Lu) have been systematically investigated by means of 57Fe Mossbauer spectroscopy. It is shown that relatively large differences in effectiv

On excitation to its triplet state, aniline is distorted with a loss of the in-plane two-fold symmetry axis. The energies of the three spin components in zero field at 1.2 K correspond to Z ' = 2285 ± 10, Y ' = 174 ± 10, X ' = −2459 ± 10 MHz; th

It is shown that the spin-spin and spin-lattice relaxation rates in the lowest triplet state of aniline in a p -xylene host crystal are determined by the presence of a close-lying local phonon state. It is concluded that the motion of the aniline mol

A magnetic resonance study is reported of the 3 Eu state of zinc porphin in an n-octane host in zero field from 1·2 K to 65 K. The temperature dependence is caused by an exchange process between the two orbital components of the 3 Eu state. Spin-lat
