| Abstract: | Co-authors: Monika Løberg (University of Oslo), Nicholas Pike (University of Oslo) Phase transformation materials (PTMs) can be used for energy harvesting of heat from low-temperature heat sources if the phase transformation is accompanied by an abrupt jump in a physical property like magnetization or polarization. In addition, the temperature hysteresis should be low in order to prevent losses. The criteria for this supercompatibility can be described in terms of the crystal structure of the phases. We are exploiting this in a new project where we are using various experimental and theoretical high-throughput techniques to search for unknown PTMs with very low hysteresis and a large change in potential energy. Some preliminary results are shown and discussed in light of the recent international progress in the field.
