Controlling a phase of matter by coherently manipulating specific vibrational modes has
long been an attractive (yet elusive) goal for ultrafast science. Solids with strongly correlated …

Controllable switching between metastable macroscopic quantum states under
nonequilibrium conditions induced either by light or with an external electric field is rapidly …

Persistent and reversible optical phase control has been achieved in a manganite thin film
through a careful choice of the composition of Pr 1-x (Ca 1-y Sr y) x MnO 3 near a …

Ultrafast melting of a charge-ordered state has been observed in the photo-irradiated
colossal magnetoresistive compound Pr 0.7 Ca 0.3 MnO 3. Pump-and-probe spectroscopy …

Photoinduced effects on the charge-and orbital-ordered (CO/OO) states in a layered
perovskite manganite La 0.5 Sr 1.5 MnO 4 have been investigated with femtosecond …

Terahertz THz radiation with its spectrum extending up to 1 THz has been observed by an

Femtosecond reflection spectroscopy was performed on a perovskite-type manganite, Gd
0.55 Sr 0.45 MnO 3, with the short-range charge and orbital order (CO/OO). Immediately …

Persistent ferromagnetic magnetization (M) as large as 0.6 μ B per Mn site can be induced
by irradiating visible laser pulses on a thin film of 1% Cr-doped Pr 0.5 Ca 0.5 MnO 3. The …

We report melting of the charge-ordered state in low bandwidth manganite PCMO (x= 0.3–
0.5) thin films under substantially lower magnetic field. Two different in situ post-deposition …

In transition metal oxides, the potential of competing energetics of interacting fundamental
entities is best displayed in perovskite manganites via the formation of a variety of exotic …
