Small-scale phase separation in doped anisotropic antiferromagnets
M. Yu. Kagan, K. I. Kugel, A. L. Rakhmanov +1
We analyze the possibility of the nanoscale phase separation manifesting itself in the formation of ferromagnetic (FM) polarons (FM droplets) in the general situation of doped anis…
Quantum Tera-Hertz electrodynamics in Layered Superconductors
Sergey Savel'ev, A. L. Rakhmanov, Franco Nori
In close analogy to quantum electrodynamics, we derive a quantum field theory of Josephson plasma waves (JPWs) in layered superconductors (LSCs), which describes two types of inter…
Nonuniform Self-Organized Dynamical States in Superconductors with Periodic Pinning
V. R. Misko, S. Savel'ev, A. L. Rakhmanov +1
We consider magnetic flux moving in superconductors with periodic pinning arrays. We show that sample heating by moving vortices produces negative differential resistivity (NDR) of…
A new type of bound magnetic polaron state: the formation of long-range spin distortions
S. L. Ogarkov, M. Yu. Kagan, A. O. Sboychakov +2
The structure of bound magnetic polarons in an antiferromagnetic matrix is studied in the framework of two-dimensional (2D) and three-dimensional (3D) Kondo-lattice models in the d…
Jahn-Teller distortions and phase separation in doped manganites
A. O. Sboychakov, K. I. Kugel, A. L. Rakhmanov
A "minimal model" of the Kondo-lattice type is used to describe a competition between the localization and metallicity in doped manganites and related magnetic oxides with Jahn-Tel…
