摘要：

The intense anisotropic magnetic resonance signals have been observed in oxygen deficient (123) compounds of high temperature superconductors at X- and Q-bands. The oxygen deficiency have been created by quenching from temperature 500-800-degrees-C. The strong temperature dependences of g-factors and a totally different behaviour of the magnetic resonance signals at X- and Q-bands have been observed. We conclude that the magnetic resonance signal belong to clusters with magnetic ordering. After rotation of the crystal the broadening of the magnetic resonance line and the relaxation of the magnetic resonance signal have been seen in the samples quenched from the temperature below 700-degrees-C. This result is a clear manifestation of pinning flux motion on the clusters with magnetic ordering.
