The metal–insulator transition (MIT) in correlated materials is a novel phenomenon that
accompanies a large change in resistivity, often many orders of magnitude. It is important in …

Spin-phonon coupling (SPC) plays a critical role in numerous intriguing phenomena of
transition metal oxides (TMOs). In 3d and 4 d TMOs, the coupling between spin and lattice …

Spin-lattice (SL) coupling plays an important role in spintronic applications given its effects
on magnetic, ferroelectric, optical, and thermodynamic properties. Experiments and …

We report polarization-resolved Raman scattering measurements on single crystals of the
pyrochlore compound Eu 2 Ir 2 O 7 which exhibits a ground state with noncollinear magnetic …

In this work, we report low-temperature Raman spectroscopic measurement to investigate
the temperature dependence of phonons and magnetic as well as electronic excitations in …

Elementary quasiparticles in solids such as phonons and magnons occasionally have
nontrivial interactions between them, as well as among themselves. As a result, their energy …

Abstract 5 d pyrochlore oxides with all-in-all-out magnetic order are prime candidates for
realizing strongly correlated, topological phases of matter. Despite significant effort, a full …

We utilize near-infrared femtosecond pulses to investigate coherent phonon oscillations of
Ca 2 RuO 4. The coherent A g phonon mode of the lowest frequency changes abruptly not …

Coupling of orbital degree of freedom with a spin exchange, ie, Kugel-Khomskii-type
interaction (KK), governs a host of material properties, including colossal …

In order to explore the consequences of spin–orbit coupling on spin–phonon interactions in
a set of chemically similar mixed metal oxides, we measured the infrared vibrational …
