Photoinduced absorption and anomalous dichroism in NaCa₂Mn₂V₃O₁₂ garnet as an evidence for the formation of oxygen holes dynamics

Autor: Eremenko, V.V., Gnatchenko, S.L., Kachur, I.S., Piryatinskaya, V.G., Ratner, A.M., Shapiro, V.V., Kosmyna, M.B., Nazarenko, B.P., Puzikov, V.M.

It is shown that long-lived photoinduced dichroism in garnets is caused by photoproduced charges with anisotropic structure, keeping long memory of the pumping light polarization, while photoinduced absorption is due to all photoproduced charges irre

Coherent motion and anomalous transport properties of exciton and hole polarons with intrinsic vibrationa

Autor: Ratner, A.M.

It is shown that intrinsic vibrational degrees of freedom, inherent in two-atom exciton and hole polarons, drastically affect their transport properties in wide-band dielectrics (rare-gas solids and alkali halides). A fast excitonic energy transport

Photoinduced light absorption and dichroism of Ca₃Mn₂Ge₃O₁₂ garnet as a probe of electronic processes and intrinsic electric fields

Autor: Eremenko, V.V., Gnatchenko, S.L., Kachur, I.S., Piryatinskaya, V.G., Ratner, A.M., Shapiro, V.V., Fally, M., Rupp, R.A.

Measurements of photoinduced light absorption in Ca₃Mn₂Ge₃O₁₂ revealed some unusual features: a saturation with the pumping intensity and a broad straggling of relaxation times with a predominance of very long times. These experimental fact
