Polaron formation in the optimally doped ferromagnetic manganites La0.7Ba0.3MnO3 and La0.7Ba0.3MnO3
Y. Chen, B. G. Ueland, J. W. Lynn +3
The nature of the polarons in the optimally doped colossal magnetoresistive (CMR) materials La0.7Ba0.3MnO3 (LBMO) and La0.7Sr0.3MnO3 (LSMO) is studied by elastic and inelastic neut…
Magnetization and Magnetotransport of LnBaCo2O5.5 (Ln=Gd, Eu) Single Crystals
Z. X. Zhou, S. McCall, C. S. Alexander +6
The magnetization, resistivity and magnetoresistance (MR) of single crystals of GdBaCo2O5.5 and EuBaCo2O5.5 are measured over a wide range of dc magnetic fields (up to 30 T) and te…
Phonon Raman scattering in LaMn1-xCoxO3 (x = 0, 0.2, 0.3, 0.4, and 1.0)
V. P. Gnezdilov, Yu. G. Pashkevich, A. V. Yeremenko +5
The Raman-active phonons in perovskite-like LaMn1-xCoxO3 (x = 0, 0.2, 0.3, 0.4, and 1.0) were studied by measuring Raman spectra at temperatures of 295 and 5 K. The changes in the…
