Magneto-optical properties of (Ga,Mn)As: an ab--initio determination

A. Stroppa, S. Picozzi, A. Continenza +2

The magneto-optical properties of (Ga,Mn)As have been determined within density functional theory using the highly precise full-potential linear augmented plane wave (FLAPW) method…

Interface effects at a half-metal/ferroelectric junction

Kunihiko Yamauchi, Biplab Sanyal, Silvia Picozzi

Magnetoelectric effects are investigated ab-initio at the interface between half-metallic and ferroelectric prototypes: Heusler CoMnSi and perovskite BaTiO. For the Co-term…

Optical and magneto-optical properties of ferromagnetic full-Heusler films: experiments and first-principles calculations

F. Ricci, S. Picozzi, A. Continenza +5

We report a joint theoretical and experimental study focused on understanding the optical and magneto-optical properties of Co-based full-Heusler compounds. We show that magneto-op…

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…

Role of the electric field in surface electron dynamics above the vacuum level

J. I. Pascual, C. Corriol, G. Ceballos +6

Scanning tunneling spectroscopy (STS) is used to study the dynamics of hot electrons trapped on a Cu(100) surface in field emission resonances (FER) above the vacuum level. Differe…

A local field emission study of partially aligned carbon-nanotubes by AFM probe

A. Di Bartolomeo, A. Scarfato, F. Giubileo +5

We report on the application of Atomic Force Microscopy (AFM) for studying the Field Emission (FE) properties of a dense array of long and vertically quasi-aligned multi-walled car…
