| Popis: | Using neutron diffraction data, the thermal evolution of the magnetic structure of Ho3Fe5O12 has been studied. Below the compensation temperature (Tcomp=137 K), the umbrella structure parameters which fit the spontaneous ferrite magnetizations have been determined. AboveTcomp, the compound behaves as a Neel type ferrimagnet. Particular attentions have been given to the magnetic form factors of both iron sublattice on one hand and on the other hand to a rhombohedral distorsion fromI a3d toR\(\bar 3\) below 30 K and in first approximation toR\(\bar 3\)c forT>30 K. |
