| Abstract: | Semi-dilute 10% 63Cu : Zn(pyO)6(ClO4)2 pyO = C5H5NO, pyridine-N-oxide] has been studied by EPR. Spectra of pairs of Cu(pyO)2+6 ions are observed below the transition from dynamic to static Jahn-Teller distortion. Most of these pairs are antiferrodistortively oriented. They exhibit only the type of exchange which corresponds to the interchain interaction J′ in the pure Cu compound. From the Q-band AB type of spectrum it was found that |J′|/k = 0.041 K. An estimate of the zero- point spin reduction could be derived (～36%). |
