Colossal magnetoresistive manganite thin films
Mixed-valence perovskite manganites (Re 1−x A x MnO 3 where Re=rare earth, A=alkaline earth) provide a unique opportunity to study the relationships between the structure and the magnetotransport properties due to an interplay among charge carriers, magnetic coupling, orbital ordering and structural distortion. This makes these compounds very exciting from both the basic research and from the t...
متن کاملTHz-Wave Generation in a Magnetoresistive Manganite Pr0.7Ca0.3MnO3
We discovered the THz-wave generation from the voltage applied optical switching device made on a magnetoresistive manganite Pr0.7Ca0.3MnO3 excited by the femtosecond optical pulses. Its spectrum extends up to 1 THz centered at around 0.2 THz. The generation efficiency (η) linearly depends on both external stimulation. It is also shown that η strongly depends on temperature and the trend of η(T...
متن کاملMeasurement of dielectric properties at low temperatures: application to the study of magnetoresistive manganite/ insulating oxide bulk composites
In this paper, we report low temperature dielectric measurements of bulk composite electroceramic samples containing a colossal magnetoresistive (CMR) manganite phase (La0.7Ca0.3MnO3 [abbreviated LCMO]) and an insulating phase (Mn3O4). Details of the experimental system are given and possible experimental artefacts due to moisture are outlined. For a LCMO volume fraction of ~ 16%, the permittiv...
متن کاملElectronic properties of Si/Si12x2yGexCy heterojunctions
We have used admittance spectroscopy and deep-level transient spectroscopy to characterize electronic properties of Si/Si12x2yGexCy heterostructures. Band offsets measured by admittance spectroscopy for compressively strained Si/Si12x2yGexCy heterojunctions indicate that incorporation of C into Si12x2yGexCy lowers both the valenceand conduction-band edges compared to those in Si12xGex by an ave...
متن کاملTemperature dependent evolution of the electronic and local atomic structure in the cubic colossal magnetoresistive manganite La1-xSrxMnO3
We have studied the temperature-dependent evolution of the electronic and local atomic structure in the cubic colossal magnetoresistive manganite La1-xSrxMnO3 (x= 0.3 – 0.4) with core and valence level photoemission (PE), x-ray absorption specroscopy (XAS), x-ray emission spectroscopy (XES), resonant inelastic x-ray scattering (RIXS), extended x-ray absorption fine structure (EXAFS) spectroscop...
