Abstract
We report the frequency and magnetic-field dependence of the microwave absorption in ErBa2Cu3Ox for 1.3 K < T < 100 K. At temperatures below about 10 K, there is a huge increase in the absorption at zero field. Surprisingly, this giant effect comes from the electron spin resonance involving the lowest-lying Kramers doublet of the Er3+ ion. The ESR is broad and highly distorted, presumably due to a wide distribution of slowly varying dipolar fields which, in turn, leads to an effective zero field splitting of about 1 K.
