Element-resolved ultrafast magnetization dynamics in ferromagnetic alloys and multilayers
… interaction that couples the Ni and Fe sublattices under equilibrium conditions. Furthermore, the time constants of demagnetization for Ni and Fe are different in Ni50Fe50 and Ni80Fe20, and also different from the values for the respective pure elements. These variations are explained by …

Imaging magnetic order in magneto-structural phases of Mn3O4
Frustration in A-site spinels due to the competition between complex structure and strong interactions has been the focus of many theoretical and experimental studies recently. Mn3O4 is one such material with a three way interplay between complex lattice geometry, strong spin-lattice coupling and …

Neutron Scattering Studies of Unusual Spin Structure and Local Correlation in Complex Oxides
… ground states that result from the close coupling between charge, lattice, orbital, and spin degrees of freedom, which can be tuned by chemical substitution, strain induction, or by the application of external stimulus (e.g. pressure, temperature, electric, or magnetic fields). Interest in …

Raman scattering studies of spinels CoV2O4 and MnV2O4
… scattering studies of the strongly correlated spinels CoV2O4 and MnV2O4. In CoV2O4, exclusive attention is given to a triply degenerate (T2g) phonon in order to determine the material's structural properties and explore coupling between the lattice and other degrees of freedom. …
