Electronic and magnetic properties of the interface LaAlO/TiO-anatase from density functional theory
Mariana Weissmann Valeria Ferrari
Ab initio calculations using the local spin density approximation and also including the Hubbard have been performed for three low energy configurations of the interface betwee…
Ab initio study of magnetism at the TiO2/LaAlO3 interface
Mariana Weissmann, V. Ferrari, Andres Saul
In this paper we study the possible relation between the electronic and magnetic structure of the TiO2/LaAlO3 interface and the unexpected magnetism found in undoped TiO2 films gro…
Magnetism in a TiO2/LaAlO3 heterostructure: an ab initio study about the role of oxygen vacancies
Valeria Ferrari, Mariana Weissmann
In this work we study the electronic structure and magnetism of a TiO2 film grown on another non-magnetic oxide such as a LaAlO3 (001) substrate, concentrating on the role played b…
Ab initio study of ferromagnetism induced by magnetic impurities in rutile TiO2
L. A. Errico, M. Weissmann, M. Renteria
Using the first-principles density-functional approach, magnetic properties of Mn-, Fe-, Co-, and Ni-doped rutile TiO2 were investigated for two different impurity concentrations (…
The role of vacancies, impurities and crystal structure in the magnetic properties of TiO2
Mariana Weissmann, Leonardo A. Errico
We present an ab initio study of pure and doped TiO2 in the rutile and anatase phases. The main purpose of this work is to determine the role played by different defects and differ…
Appearance of room temperature ferromagnetism in Cu-doped TiO films
S. Duhalde, M. F. Vignolo, C. Chiliotte +6
In recent years there has been an intense search for room temperature ferromagnetism in doped dilute semiconductors, which have many potentially applications in spintronics and opt…
