Low temperature thermal diffusivity of LiKSO4 obtained using the photoacoustic phase lag method

This paper describes the determination of the thermal diffusivity of LiKSO4 crystals using the photoacoustic phase lag method, in the 77 K to 300 K temperature interval. This method is quite simple and fast and when it is coupled to a specially designed apparatus, that includes a resonant photoacou...
