Abstract
,High-quality c-axis oriented YNi2B2C (transition temperature T-c=15K) and ErNi2B2C (T-c=9.5K) borocarbide superconducting thin films were grown "in-s itu" on MgO and sapphire substrates by planar magnetron sputtering. Here we report data on the temperature, DC and RF magnetic field dependent surface impedance of the films and discuss them in view of possible applications. The YNi2B2C films displayed the behavior expected for BCS-like superconduct ors, while the microwave response of the antiferromagnetically ordering com pound ErNi2B2C mas distinctly different. The field dependent surface resist ance of both types of films displayed granular effects.
