Half of the world’s CO<sub>2</sub> emissions can be attributed to heating and cooling [1]. This is primarily due to heating with natural gas and cooling with compression of greenhouse gases, which are neither environmentally friendly nor energy efficient. Therefore there is great interest in developing energy-efficient solid-state heat pumps that can replace these environmentally damaging technologies. Caloric materials are at the core of novel solid-state heat-pump technologies, and neutron scattering provides a unique tool for their in-operando study of structure and dynamics. During this talk I will describe our work on field-driven phase transitions in caloric materials, by combining calorimetric and neutron scattering techniques.<br/><br/>[1] Climate change: science and solutions low-carbon heating and cooling, Royal Society, 2021.
