Abstract
We have used an ESR spectrometer to study magnetism and superconductivity in YBa2Cu3O7−xSx (x=0, 1). All samples exhibited an ESR signal. All the superconducting samples showed a low-field signal due to transition from the Meissner state to the mixed state. We demonstrated a reverse relation between magnetism (ESR intensity) and superconductivity. The temperature dependence of the critical field Hc1 is anomalous.
