Charge stacking in the half-doped manganites
The stability of the charge-stacked structure vis-à-vis the charge-alternate structure in the half-doped manganites is studied with a model that includes electronic kinetic energy, onsite and intersite Coulomb interactions, the Jahn–Teller energy, and the antiferromagnetic superexchange between the manganese core spins. It is shown that for a single zigzag chain, the electronic kinetic energy s...
متن کاملBuckling-induced Zener polaron instability in half-doped manganites
By calculating the electronic, orbital, magnetic, and lattice structure of half-doped manganites we establish the central role of oxygen buckling caused by the tilting of the MnO6 octahedra, which is, in essence, a steric effect. The buckling itself does not change the Mn-Mn bonds. Instead, it drives the system toward an instability where these bonds can dimerize. In the presence of electron-el...
متن کاملCharge and magnetic ordering in two-orbital double-exchange model for manganites
Phase digram of half-doped perovskite manganites is studied within the extended double-exchange model. To demonstrate the role of orbital degrees of freedom both oneand two-orbital models are examined. A rich phase diagram is obtained in the mean-filed theory at zero temperature as a function of J (antiferromagnetic (AFM) superexchange interaction) and V (intersite Coulomb repulsion). For the o...
متن کاملJahn-Teller Effect and Superexchange in Half-Doped Manganites
We investigate the stability of the charge exchange (CE) phase within a microscopic model which describes a single plane as in La0.5Sr1.5MnO4. The model includes Coulomb interactions (on-site and intersite), the Jahn-Teller term and the superexchange interactions due to eg and t2g electrons. By investigating the phase diagram at T = 0 in mean-field approximation we conclude that the superexchan...
متن کاملThe role of Coulomb correlation in magnetic and transport properties of doped manganites: La0.5Sr0.5MnO3 and LaSr2Mn2O7
Results of local spin-density approximation (LSDA) and LSDA+U calculations of the electronic structure and magnetic configurations of the 50% hole-doped pseudocubic perovskite La0.5Sr0.5MnO3 and double-layered LaSr2Mn2O7 are presented. We demonstrate that the on-site Coulomb correlation (U ) of Mn d electrons has a very different influence on the (i) band structures, (ii) magnetic ground states...
