Vanadium-doped HfO, multiferroic uncompromised
Vincenzo Fiorentini, Paola Alippi, Gianaurelio Cuniberti
Ab initio density-functional calculations show that orthorhombic Pca21 hafnia HfO2 mixed with vanadium at low concentration is a ferroelectric and ferromagnetic insulator. The mult…
Disclosing the nature of asymmetric interface magnetism in Co/Pt multilayers
Adriano Verna, Paola Alippi, Francesco Offi +9
Nowadays a wide number of applications based on magnetic materials relies on the properties arising at the interface between different layers in complex heterostructures engineered…
Multi-gap absorption in CaCuTiO and the predictivity of ab initio methods
Francesco Ricci, Paola Alippi, Alessio Filippetti +1
We report the electronic properties of the quadruple perovskite CaCuTiO as obtained via several density-functional based methods, and propose a new interpretatio…
Impurity-vacancy complexes and ferromagnetism in doped sesquioxides
Paola Alippi, Maura Cesaria, Vincenzo Fiorentini
Based on hybrid density-functional calculations, we propose that ferromagnetism in the prototypical bixbyite sesquioxide InO doped with Cr is due to Cr-oxygen vacancy compl…
Magnetism and unusual Cu valency in quadruple perovskites
P. Alippi, V. Fiorentini
We study a selection of Cu-containing magnetic quadruple perovskites (CaCuTiO, LaCuFeO, and YCuCoO) by ab initio calculatio…
