M. Bertolotti et al., THERMAL CHARACTERIZATION OF HIGH T-C SUPERCONDUCTORS THROUGH THE PHOTODEFLECTION METHOD, Journal of thermal analysis, 47(1), 1996, pp. 67-74
The photothermal deflection method has been used for thermal diffusivi
ty measurements on bulk YBCO and BISCCO high T-c superconductors. A cr
yostat set up is used to perform photothermal measurements from room t
emperature down to 77 K.
