Quantum paraelectrics have high constant permittivity at the temperature below 10 K. Some quantum paraelectrics transit to quantum ferroelectrics, whose permittivity has temperature dependance at cryogenic temperature region by doping. We are developing the microcalorimeters using quantum ferroelectrics. In this presentation, we report on detection of alpha rays by dielectric microcalorimeters.
