Abstract

We report on measurement of the microwave surface resistance Rs at 48 GHz on a BSCCO (2212 phase) crystal. We describe the procedure developed to perform measurements on crystals by the use of a resonant cavity with end-wall-replacement technique. The measurements are taken as a function of the temperature, magnetic field and angle θ & between the field orientation and the (a,b) planes. The measured Rs is strongly anisotropic. The overall angular behavior reasonably follows the sinθ scaling rule, but deviation from this simple behavior appears approaching the parallel orientation. When the field is parallel to the (a,b) planes, a local maximum is observed in Rs, instead of a minimum. Finally, we show that the magnetic field dependence of Rs cannot be easily reconciled with existing theories for the motion of rigid flux lines.
