The observation of spin dephasing in an ensemble of dipolar coupled A and B spins is reported. In CaO crystals, the A-spin species are photoexcited S=1, F22+ centers and the group of B spins consists of S=1 / 2, F+ centers. Measurements were made at different temperatures and magnetic field strengths with use of coherent optical-microwave spectroscopy. For the first time, the results show that the A-spin dephasing is influenced by exchange narrowing in the B-spin ensemble.
