The ability to control magnetic performance using external stimuli such as temperature, pressure, magnetic field and elemental composition, is increasingly important for the development of technological materials and devices. We investigated the magneto- elastic coupling in the layered structure systems and control the magnetic states in purpose-designed magnetic materials using these four inter-related dimensions (such as temperature, pressure, magnetic field and composition). Our research focuses on tailoring magneto-elastic behaviour in rare-earth compounds to improve their physical responses. This will lead to enhanced potential for practical applications in the fields of solid-state refrigeration, magnetic sensors, switches and actuators. In this talk, we investigated the correlation between the variation of magnetic states, the 3d electronic structure and magneto-elastic coupling by combining various advanced experimental methods (X-ray/neutron powder diffraction, magnetic, electric and thermal properties characterization) and first principles calculations. We also discussed the applications of X-ray and neutron diffraction in our recent study of some selected tthermoelectric materials.
