Abstract
The electrical responses to infrared radiation of high-Tc LnBa2Cu3Oy (Ln=Y, Eu) thin films with various crystal orientations and a wide range of critical current densities are studied using modulated laser light (λ=1.3 µm). All films show clear nonobolometric responses with an order of magnitude comparable to that of bolometric responses at temperatures below Tc. The strong correlation between the responsivity of the nonbolometric response and the Cooper pair density among various oxide superconductors confirms that the nonbolometric response is due to nonequilibrium gap suppression. The cutoff frequency for a bolometric response of higher than 1 MHz and the observed film temperature rise mostly agree with values estimated assuming a microbolometer thermally linked to the substrate.
