Abstrakt: The temperature dependencies of the spin–lattice relaxation time and the phase relaxation time of 53Cr3+ ion in the Y228SiO5 single crystal are measured at the anti-crossing point via pulsed electron paramagnetic resonance technique at X-band frequencies and in the temperature range from 5 to 80 K. It is found that the phase relaxation time does not change rapidly near the anti-crossing point, whereas in optical experiments with rare-earth ions, the phase relaxation time decreases significantly with a slight deviation of the magnetic field from the anti-crossing point. The effect of spin dynamical decoupling on the phase relaxation time is measured using the Carr–Purcell–Meiboom–Gill (CPMG) multi-pulse sequence. [ABSTRACT FROM AUTHOR]
