Characteristics of the phase-separated state in manganites: Relationship with transport and magnetic properties
Autor: M. Yu. Kagan, A. L. Rakhmanov, Aleksei V. Klaptsov, I. V. Brodsky, A. O. Sboychakov, K. I. Kugel
Publikováno v: Journal of Experimental and Theoretical Physics. 98:572-581
The temperature and magnetic field dependence of the resistivity, magnetoresistance, and magnetic susceptibility of phase-separated manganites in the temperature range corresponding to nonmetallic behavior are considered within the framework of a mod

Autor: K. I. Kugel, A. L. Rakhmanov, Aleksei V. Klaptsov, Maksim Yu. Kagan, Il’ya V. Brodskii, Artem O. Sboichakov
Publikováno v: Physics-Uspekhi. 46:851-856
The magnetoresistance and the noise power of non-metallic phase-separated manganites are studied. The material is modelled by a system of small ferromagnetic metallic droplets (magnetic polarons or ferrons) in an insulating matrix. The concentration

Spin-Dependent Transport in Phase-Separated Manganites
Autor: A. L. Rakhmanov, A. O. Sboychakov, K. I. Kugel, Aleksei V. Klaptsov, M. Yu. Kagan, I. V. Brodsky
Publikováno v: Physics of Spin in Solids: Materials, Methods and Applications ISBN: 1402022255
Starting from the assumption that ferromagnetically correlated regions exist in manganites even in the absence of long-range magnetic order, we construct a model of charge transfer due to the spin-dependent tunnelling of charge carriers between such

Composite Fermions and Quartets in Optical Traps and in High-Tc Superconductors
Autor: M. Yu. Kagan, I. V. Brodsky, Dmitry V. Efremov, Roland Combescot, Xavier Leyronas, Aleksei V. Klaptsov
Publikováno v: AIP Conference Proceedings.
We consider a possibility of the creation of composite fermions in optical traps and in high‐Tc superconductors. For optical traps we study a model of Fermi‐Bose mixture with resonant attraction between particles of different sorts. In this case
