Effects of dc transport current on low-field microwave-absorption in ceramic superconducting YBCO samples

The effects of dc transport current on low-field microwave absorption have been investigated systematically on bulk ceramic YBa<sub>2</sub>Cu<sub>3</sub>O<sub>7</sub>-δ samples. At a fixed temperature T, the critical current Ic (T) at which the electron paramagnet...
