The zero-field paramagnetic resonance frequencies of Gd3+ diluted in the sulphate octohydrates of yttrium, samarium and neodymium have been measured directly at 4.2°, 80° and 273 °K. The spin Hamiltonian is of the predominantly axial type and the

The spin-Hamiltonian coefficients for Fe3+ in sapphire have been redetermined by the classical paramagnetic resonance method. The value of g is 2.0026±0.0005 and is independent of temperature. The other coefficients, in units of 10-4 cm-1, and for t

A double resonance experiment on natural mercury is described. The value of the hyperfine structure coupling constant of the 6s6p3P1 level of 199Hg obtained is 0.497 ± 0.014 cm-1.

The need for direct measurements of paramagnetic resonance absorption spectra in zero magnetic field is discussed. Two spectrometers have been built which together cover the range of 8 to 18 Gc/s; with one of these a spectrum is recorded over a range

A survey is made of the available ways of using ruby, spinel, rutile and emerald in masers which amplify at frequencies small compared to their zero-field splitting frequencies. Particular attention is paid to means of taking advantage of cross relax

The splitting of the ground level of Fe3+ in (CH3NH3)Al(SO4)2. 12H2O in the absence of a magnetic field has been measured directly. At 90 °K the separation of the SZ = ± 3/2 states from the ±1/2 is equivalent to 12 227 ±5 Mc/s, and that of the ±

The Schottky specific heat anomaly of gadolinium sulphate octohydrate is calculated from the recent microwave measurements of the ground-state splittings. The results are tabulated for a number of temperatures between 0.05° and 4.0 °K, together wit
