The phase - separated states in antiferromagnetic semiconductors with polarizable lattice
نویسنده
چکیده
The possibility of the slab or stripe phase separation (alternating ferromagnetic highly-conductive and insulating antiferromagnetic layers) is proved for isotropic degenerate antiferromagnetic semiconductors. This type of phase separation competes with the droplet phase separation (ferromagnetic droplets in the antiferromagnetic host or vice versa). The interaction of electrons with optical phonons alone cannot cause phase-separated state with alternating highly-conductive and insulating regions but it stabilizes the magnetic phase separation. The magnetostriction deformation of the lattice in the phase-separated state is investigated.

Comment on ‘ Phase - separated states in antiferromagnetic semiconductors with a polarizable lattice ’
The 'proof' of the possibility of the slab or stripe phase separation in polar semiconductors, proposed recently by E. 014401) is shown to be erroneous. The fundamental error originates in the double-counting of the electron-phonon interaction with optical phonons.
متن کاملA ug 2 00 2 On the absence of conduction electrons in the antiferromagnetic part of the phase - separated states in magnetic semiconductors ∗
We have calculated the energies of the phase-separated states for degenerate antiferromagnetic semiconductors including the possibility of the existence of conduction electrons in the antiferromagnetic part of the phase-separated states. It is demonstrated that, at T = 0, the minimum energy corresponds to a droplet phase with absence of electrons in the antiferromagnetic part.
متن کاملDimerized phase and transitions in a spatially anisotropic square lattice antiferromagnet.
We investigate the spatially anisotropic square lattice quantum antiferromagnet. The model describes isotropic spin-1/2 Heisenberg chains (exchange constant J) coupled antiferromagnetically in the transverse (J( perpendicular )) and diagonal (J(x)), with respect to the chain, directions. Classically, the model admits two ordered ground states-with antiferromagnetic and ferromagnetic interchain ...
متن کاملInvestigation of effect of magnetic ordering on structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) using ab initio method
Structural and electronic properties of double perovskites Sr2BWO6 (B = Co, Ni, Cu) were studied for each of three magnetic configurations nonmagnetic, ferromagnetic, and antiferromagnetic by using density functional theory in generalized gradient approximations (GGA) and strong correlation correction (GGA + U). Due to magnetic transition from antiferromagnetic to nonmagnetic phase, an electr...
متن کاملPhase evolution of the two-dimensional Kondo lattice model near half-filling.
Within a mean-field approximation, the ground state and finite temperature phase diagrams of the two-dimensional Kondo lattice model have been carefully studied as functions of the Kondo coupling J and the conduction electron concentration [Formula: see text]. In addition to the conventional hybridization between local moments and itinerant electrons, a staggered hybridization is proposed to ch...
