Anomalous multi-order Raman scattering in LaMnO_3: a signature of a quantum lattice effect in a Jahn-Teller crystal
N. N. Kovaleva, O. E. Kusmartseva, K. I. Kugel +8
The multi-order Raman scattering is studied up to a fourth order for a detwinned LaMnO_3 crystal. Based on a comprehensive data analysis of the polarisation-dependent Raman spectra…
Formation of metallic magnetic clusters in a Kondo-lattice metal: Evidence from an optical study
N. N. Kovaleva, K. I. Kugel, A. V. Bazhenov +5
Magnetic materials are usually divided into two classes: those with localised magnetic moments, and those with itinerant charge carriers. We present a comprehensive experimental (s…
Effect of electron-lattice interaction on the phase separation in strongly correlated electron systems with two types of charge carriers
A. O. Sboychakov, A. L. Rakhmanov, K. I. Kugel
The effect of electron-lattice interaction is studied for a strongly correlated electron system described by the two-band Hubbard model. A two-fold effect of electron-lattice inter…
Resistivity and 1/f Noise in Non-Metallic Phase Separated Manganites
A. L. Rakhmanov, K. I. Kugel, Ya. M. Blanter +1
A simple model is proposed to calculate resistivity, magnetoresistance, and noise spectrum in non-metallic phase-separated manganites containing small metallic droplets (magnetic p…
