    Effect of swift heavy ion irradiation on surface resistance of DyBa2Cu3O7-δ thin films at microwave frequencies

    We report the observation of a propounced peak in surface resistance at microwave frequencies of 4.88 GHz and 9.55 GHz and its disappearance after irradiation with swift ions in laser ablated DyBa2Cu3O7-δ (DBCO) ...
