Title: A cryostatic setup for the low-temperature measurement of thermal diffusivity with the photothermal method

Abstract

A cryostatic setup is described to perform photothermal deflection measurements from room temperature to 77 K. The setup uses gaseous nitrogen as a medium where the photodeflection is produced. The ability of the system to work is demonstrated presenting some measurements of thermal diffusivity of high-temperature superconductor samples and of yttrium-iron garnets with variable aluminum content. {copyright} {ital 1995} {ital American} {ital Institute} {ital of} {ital Physics}.
