Strongly correlated electron systems often exhibit very strong interactions between structural
and electronic degrees of freedom that lead to complex and interesting phase diagrams,. For …

We present a rationalization of the Raman spectra of orthorhombic and rhombohedral,
stoichiometric and doped, manganese perovskites. In particular, we study R MnO 3 (R= La …

Two series of elpasolite perovskites Ln2CoMnO6 and Ln2NiMnO6 (Ln= La, Pr, Nd, Sm, Gd)
have been prepared. The electronic band gap and magnetic Curie temperature vary …

We use femtosecond x-ray diffraction to probe directly the structural dynamics of a charge
ordered and orbitally ordered thin film of La 0.42 Ca 0.58 MnO 3 initiated by an ultrafast …

The metal-insulator transition is characterized as a single peak in the temperature-
dependent resistivity measurements; exceptions to this have never been seen in any single …

Abstract A-site deficient (La 0.6 Sr 1.4) 0.95 Mn 1-x B x O 4 (x= 0, 0.1, B= Co, Ni, Cu)(LSMBO
4) Ruddlesden–Popper oxides were demonstrated as promising symmetrical electrodes for …

We report direct evidence of the theoretically predicted electron-rich surface of doped
perovskite manganites La 0.7 A 0.3 MnO 3 (A= Ca, Sr) by means of surface-enhanced …

Spontaneous C4-symmetry breaking phases are ubiquitous in layered quantum materials,
and often compete with other phases such as superconductivity. Preferential suppression of …

Ultrashort laser pulses have been utilized to dynamically drive phase transitions in
correlated quantum materials. Of particular interest is whether phases not achievable in …

Understanding and controlling the relaxation process of optically excited charge carriers in
solids with strong correlations is of great interest in the quest for new strategies to exploit …
