“…11,19,20 In terms of CC and EF interactions, these results imply the reasonable amount of orbital angular momentum quenching. 21,22 As it has been predicted for x = 3 9 and for x = 0.9, 4 the interpretation based on the generalized spin Hamiltonian in the hypothesis of the quasi doublet model does not seem to be valid. In fact, the quasi ground state doublet cannot account alone for <uuw> as an EAM below T SR .…”

In this work, magnetic properties of dysprosium doped yttrium iron garnet single crystals DyxY3-xFe5O12 (1 ≤ x ≤ 3) are studied in the 2-50 K temperature range under high D.C. magnetic fields H up to 16 T. When the sample is allowed to rotate freely on itself, critical points are observed and form a critical line of second order type which increases linearly with T in the magnetic phase diagram. This line is independent of the content x delimiting a canted phase which is issued from the low symmetry angular <uuw> phase occurring from the spontaneous spin reorientation below TSR (H = 0) = 14.62 K. In comparison with the free ion, the observed reduction at 0 K of the Dy3+ moments is also discussed.

Y3Fe5O12 ceramics are prepared by the solid state reaction method. Grain size and Fe2+ concentration‐dependent magnetic, dielectric, and magnetodielectric properties are investigated systematically. It is found that grain size and Fe2+ concentration increase with increasing sintering temperature, which thus results in increased saturation magnetization while decreased coercive field and remanent magnetization. Three sets of dielectric relaxation are observed in temperature range from 10 to 500 K, which are considered to be originated from quantum tunneling effect of electrons, electron hopping between Fe2+ and Fe3+, and the migration of oxygen vacancies, respectively. Cole–Cole fitting results of relaxation II indicate that a correlation exists among the hopping electrons, and the correlation is strengthened as Fe2+ concentration increases, which in turn results in easier hopping process and decreased activation energy. More interesting, YIG ceramics sintered at 1350 °C show both considerable magnetic and dielectric properties at room temperature, opening a new window for the application of YIG as a possible multi‐susceptibile single‐phase material.
