Neutron scattering can explore excitations of magnetic materials with the energy scale from μeV to eV. Neutron instruments in the large scale national facility ANSTO will be used to investigate the magnetic excitations of new novel perovskite systems. An example is described below.

Unconventional superconductors, multiferroics, and frustrated magnets constitute a class of magnetic materials that play an important role in diverse branches of condensed matter physics. These systems embody the complex interplay of charge, spin, orbital, and lattice degrees of freedom. Understanding fundamental physical laws of these systems can provides a pathway toward the development of next-generation functional materials, such as quantum qubits, multifunctional memory devices, and environmentally sustainable solid-state refrigeration technologies.
The present project, the magnetic excitations in new series of perovskite oxides will be investigated by means of inelastic neutron scattering techniques. By accurately measuring and analyzing the magnetic excitations, new classes of interactions can be uncovered. Using density functional theory, accurate quantum mechanical calculations will also be performed to assist in the interpretation of the measured results. A deeper understanding of these interactions broadens the prospects for controlling physical properties of magnetic material through magnetic field, electric field, and other physical parameters.
