Zusammenfassung:	The authors have been measuring the bulk electrical and thermal properties of the quantum ferroelectric KTa[sub 0.992]Nb[sub 0.008]O[sub 3] (KTN) in the interest of making a thermal sensor for a pyroelectric microcalorimeter. The pyroelectric coefficient and specific heat of KTN as a function of temperature and electric field are given. The measurements indicate that a thin film detector with the same pyroelectric coefficient as that found in our sample would in principle be able to operate in a phonon noise limited regime over a wide bandwidth.
