Abstract
The electron spin-lattice relaxation time T1 of (3d)4 type ion, Mn3+, in rutile was measured from 1.7 K up to 7 K by the pulse saturation recovery method. It was concluded that, in a liquid He temperature region, T1 was determined by the Orbach process via three excited levels.<BR>The anisotropy of T1 was observed at 4.2 K, although T1 by the simple Orbach process is expected to be independent of the direction of static magnetic field. In order to understand this result, we presume that the relaxation of Mn3+ ion in TiO2 is phonon-bottlenecked, suggesting stronger coupling of Mn3+ spin with the lattice than the case of Fe3+, Mn4+ or Cr3+ ions.
