Evidence for non-s-wave symmetry of the pi gap in MgB[subscript 2] from intermodulation distortion measurements

We present low-temperature low-power intermodulation-distortion (IMD) measurements of high-quality MgB[subscript 2] thin films that are inconsistent with presumed s-wave symmetry of the order parameter. The measurements were carried out in a stripline resonator at approximately 2 GHz between 1.8 K a...
