抄録

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.
