Abstract: | A crystal field analysis of the experimental data on magnetic, optical and thermal properties of Dy(OH)3 single crystals have been published The nuclear hyperfine properties of Dy3+ in Dy(OH)3 were studied using a crystal field thus obtained. The hyperfine spectra were computed from 4–20 K with a minimum number of approximations. Under a weak crystal field, the lowest electronic level is a Kramers' doublet For this highly anisotropic crystal, the magnetic hyperfine and the quadrupole interactions are both prominent The quadrupole interaction energy is temperature dependent The value of the magnetic Sternheimer factor Rhf/R is determined to be 0 14 The observed specific heat arising from hyperfine interactions have been explained satisfactorily A maxima is expected at 21 mK. |
