Precautions when interpreting EPR and dc magnetization measurements of high-T/sub c/ RBa2Cu3O/sub y/-phase superconducting materials
- 1. University of California, San Diego, La Jolla California 92093
Description
Many electron-paramagnetic-resonance (EPR) and magnetic susceptibility measurements for the high-T/sub c/ superconductors of the form RBa2Cu3O/sub 9-//sub x/ (R = Y or a rare earth) have been reported. Excluding local moment resonances due solely to the R atoms, we show that all of the EPR measurements known to us are not intrinsic to the superconducting phase, but rather are due to low concentrations of spurious phases typically present in the samples. BaCuO2 is found to be the main source of the low-temperature EPR signal and of the magnetic susceptibility which has been reported for YBa2Cu3O/sub 9-//sub x/ above T/sub c/
