Complex spin structures and multifunctional magnetism — •Vivien Zapf — National High Magnetic Field Lab, Los Alamos National Lab

There has been a recent surge of interest in multiferroics where magnetism and ferroelectricity are coupled to each other. In particular, complex magnetic spin textures such as skyrmions and other noncoplanar spin patterns can produce the necessary symmetry breaking to couple to ferroelectricity. I will discuss spatial inversion symmetry breaking in quantum and classical magnets and the microscopic coupling mechanisms between magnetism and ferroelectricity. I will review work at the National High Magnetic Field Lab, charting the phase diagrams of frustrated, quantum, and other complex spin systems to extended temperature and magnetic field which, conjunction with theory, can reveal important underlying information about the magnetic Hamiltonian.
