“…For an arbitrary orientation of an external magnetic field relative to the crystal axes the EPR spectrum of Nd3 + ions consists of six lines due to six magnetically nonequivalent positions. According to [9] g-factors for Nd 3 + in YAG are as follows: gx = 1.743, gy = 1.160, g^ = 3.908. If the magnetic field is directed along the [100] axis, the EPR spectrum consists of only two lines: a double line with g = g, and a fourfold line with g = 1.48.…”

The spin-lattice relaxation times for Nd 3 + ions in yttrium-aluminum garnets (YAG) and for Yb'+ ions in CaF 2 in the low-temperature range have been measured. For the first system the temperature dependence of the relaxation rate is determined to a great extent by the method of sample preparation. For samples grown by the method of the horizontally oriented crystallization the dependence is described as T, -' = AT", n = 4.7, which is an evidence of an influence of local structure disordering on the relaxation. The temperature dependence of the relaxation rate in CaF 2 :Yb is also "anomalous": T, -' = AT''. The results are compared with the previous data on the relaxation in similar systems, and with other cases of observation of "anomalous" temperature dependences. Different manifestations of the local crystal defects in spin-lattice relaxation are discussed.

Using the recently developed method we calculate the crystal field parameters in yttrium and lutetium aluminum garnets doped with seven trivalent Kramers rare-earth ions. We then insert calculated parameters into the atomic-like Hamiltonian taking into account the electron-electron, spin-orbit and Zeeman interactions and determine the multiplet splitting by the crystal field as well as magneticĝ tensors. We compare calculated results with available experimental data.
