Abstract
The magnetic properties of Fe-based singlecrystal garnets have been studied. A magnetic field up to 55 kOe in the temperature range from 4.5 to 300 K has been used. The compensation temperature (T comp) of the studied garnets has been determined. The compensation temperature increases with the increase of the rare-earth ions (Ho3+ or Gd3+) substituting Y3+ ions in thec sublattice of R3Fe5O12. AboveT comp, the magnetization was found to be linearly field dependent. The results are in good agreement with magnetization measurements performed on polycrystaline samples, and with calculations based on the crystal field parameters of the isostructural Holmium Gallium Garnet (HoGG).
