| Abstract: | The electron spin resonance of VO2+ is studied in single crystals of Cs2M″ (SeO4)2·6H2O (M″ = Zn, Co) from 290 to 77 K at ～ 9.45 GHz. The line broadening of VO2+ spectra on cooling the Cs2Co(SeO4)2·6H2O crystal is explained on the basis of host spin-lattice relaxation narrowing. T1 for Co2+ is estimated to be ≈ 1.7 × 10?12 sec. at 290 K. |
