Electronic self-organization in the single-layer manganite Pr1-xCa1+xMnO4.
We use neutron scattering to investigate the doping evolution of the magnetic correlations in the single-layer manganite Pr1-xCa1+xMnO4, away from the x=0.5 composition where the CE-type commensurate antiferromagnetic (AF) structure is stable. We find that short-range incommensurate spin correlations develop as the system is electron doped (x<0.5), which coexist with the CE-type AF order. This ...
متن کاملSpin, Orbital, and Spin-Orbital Polarons in Transition Metal Oxides
I give a brief overview of a polaron formation in three distinct transition metal oxides: (i) spin polaron when a hole is added to the antiferromagnetic (AF) ordered plane in La2CuO4, (ii) orbital polaron when a hole is added to the alternating orbital (AO) ordered plane in LaMnO3, and (iii) spin-orbital polaron when a hole is added to the AF and AO ordered plane in LaVO3. Comparison of the dis...

متن کاملPolaron Effects on the Stark Shift of a Bound Polaron in Finite Quantum Wells
We performed electron spin and nuclear magnetic resonance and inelastic neutron scattering measurements of a single crystal of lightly hole-doped La1−xSrxCoO3, x ∼ 0.002 in order to establish the origin of a surprisingly strong magnetization due to a very small Sr doping. The data provide experimental evidence for the creation at low temperatures of extended spin clusters with a large spin mult...
متن کاملAn Electron Paramagnetic Resonance Study of Electron-Hole Asymmetry in Charge Ordered Pr1−xCaxMnO3 (x=0.64,0.36)
We present and compare the results of temperature-dependent electron paramagnetic resonance (EPR) studies on Pr1−xCaxMnO3 for x = 0.64 which is electron-doped with those on the hole doped x = 0.36 composition. The temperature dependence of the various parameters obtained from the powder and single crystal spectra show significant differences between the two manganites. At room temperature the ‘...
