Magnetic-field- and pressure-induced quantum phases in complex materials

This Progress Report presents temperature-, magnetic-field-, and pressuredependent Raman measurements of strongly correlated materials such as the charge-ordering manganese perovskites, the multiferroic material TbMnO ₃, and the charge-density wave (CDW) materials ⌉T-TiSe ₂ and Cu_xTiSe₂. These studies illustrate the rich array of phases and properties that can be accessed with field and pressure tuning in these materials, and demonstrate the efficacy of using magnetic-field- and pressure-dependent scattering methods to elucidate the microscopic changes associated with highly tunable behavior in complex materials.
