Texto completo: acesso restrito. p. 1030-1035This paper presents the adaptation of the Preisach model, originally developed for magnetic hysteresis, to describe mathematically the hysteresis in the resistance-temperature characteristics of vanadium–dioxide VO2 thin film radiation sensors. The necessary and sufficient conditions for the applicability of the Preisach model to a (VO2) film sensor are experimentally verified. Experimentally measured characteristics are compared with those given by the model for minor and major loops
