Investigation of Ho ordering and its role in magnetization compensation in garnet, Ho3Fe5O12

Abstract: The garnet system Ho3Fe5O12 (HIG), which is ferrimagnet below 567 K, shows magnetization compensation phenomenon at 138 K (Tcomp) and another magnetic transition around 55 K corresponding to a non-collinear ordering of Ho sublattice. However, there is a discrepancy about the ordering of Ho ion with contradicting reports of Ho ordering at around 55 and 138 K. We propose to carry out neutron diffraction experiments in the temperature range of 5 – 200 K on polycrystalline HIG using GEM diffractometer to resolve the mystery of Ho ordering. The outcome of the proposed experiment will establish the role of rare-earth (Ho) magnetic ordering and its possible coupling with lattice distortions in achieving the magnetization compensation in HIG. It may provide a mean to tune the Tcomp towards room temperature of such technologically important materials with possible applications in spintronics.
