Dual nature of improper ferroelectricity in a magnetoelectric multiferroic
Silvia Picozzi, Kunihiko Yamauchi, Biplab Sanyal +2
Using first principles calculations, we study the microscopic origin of ferroelectricity (FE) induced by magnetic order in the orthorhombic HoMnO3. We obtain the largest ferroelect…
Electron Doping of Cuprates via Interfaces with Manganites
S. Yunoki, A. Moreo, E. Dagotto +3
The electron doping of undoped high- cuprates via the transfer of charge from manganites (or other oxides) using heterostructure geometries is here theoretically discussed. Th…
The Crossover from Impurity to Valence Band in Diluted Magnetic Semiconductors: The Role of the Coulomb Attraction by Acceptor
F. Popescu, C. Şen, E. Dagotto +1
The crossover between an impurity band (IB) and a valence band (VB) regime as a function of the magnetic impurity concentration in models for diluted magnetic semiconductors (DMS)…
Transport through quantum dots: A combined DMRG and cluster-embedding study
F. Heidrich-Meisner, G. B. Martins, C. A. Busser +5
The numerical analysis of strongly interacting nanostructures requires powerful techniques. Recently developed methods, such as the time-dependent density matrix renormalization gr…
Competing Ferromagnetic and Charge-Ordered States in Models for Manganites: the Origin of the CMR Effect
Cengiz Sen, Gonzalo Alvarez, Elbio Dagotto
The one-orbital model for manganites with cooperative phonons and superexchange coupling has been investigated via large-scale Monte Carlo (MC) simulations. Results fo…
