Abstract
Experiments on superconducting transition properties and power noise density experiments are performed in Ir-based transition edge sensors samples prepared by magnetron sputtering and by laser ablation techniques. The experimental temperature dependence of the resistive-superconducting transitions are compared and analyzed in terms of percolating models. Broad excess noise peak of low amplitude is detected close to the superconductive state and explained by the correlated avalanche theory.
