摘要：
The temperature dependence of the Fe-57 resonance in YBa2(Cu0.98Fe0.02)4O8 samples shows evidence of a discontinuity in the observed linewidth GAMMA(T), isomer shift, and quadrupole splitting at T(c). GAMMA(T) is found to increase precipitously at T < T(c) with the excess width DELTA-GAMMA(T) thermally activated. This behavior is a signature of a fluctuating electric-field gradient in the planes with the fluctuations slowing down in the superconducting phase,
