Neutron Scattering Study of Magnetic Phase Transitions



The major research activities involve the preparations and characterizations of novel phase-transition materials with potential refrigeration applications including barocaloric materials and magnetocaloric materials. By established strong ties with the leading large-scale facilities in the world such as CSNS, J-PARC, ANSTO, SNS, SPring-8, and SACLA, utilize neutron scattering, X-ray scattering and X-ray free-electron-laser methods, to concentrate studies on phase transitions and criticality, as well as coupling among lattice, spin, orbital and charge in diverse time and spatial scales. Correlation and interplay of these degrees of freedom create some exotic matters that can be excited and mutually transformed by application of external stimulus, from which the novel functionalities are expected. After parameterizing the performances of materials, they could be adapted to real refrigeration applications.
