Abstract

Among classical applications of superconductivity, superconductor bolometers representing a superconducting thin-film strip in the resistive state occupy an important place [1-4]. The present study concerns HTSC bolometer samples based on YBa2Cu3O7−δ with a PrBa2Cu3Ox protective layer. For the first time, the thermal resistance at the YBa2Cu3O7−δ-PrBa2Cu3Ox epitaxial interface is quantitatively estimated from the response to pulses of a Ti:Al2O3 laser as (0.3 ÷ 1.3) · 10−3 K·cm2/W.
