摘要:Abstract(#br)Magnetic mineral inclusions, as iron oxides or sulfides, occur quite rarely in natural diamonds. Nonetheless, they represent a key tool not only to unveil the conditions of formation of host diamonds, but also to get hints about the paleointensity of the geomagnetic ...

摘要:Abstract(#br)In this paper we model the magnetocaloric effect of LaFe x Mn y Si z –H 1.65 compound ( x + y + z = 13 ), a system showing a transition temperature finely tunable around room temperature by Mn substitution. The thermodynamic model takes into account the coupling...

摘要:Abstract(#br)We develop a thermodynamic model to describe antiferro- (AFM) to ferromagnetic (FM) phase transitions through magnetoelastic coupling in the framework of Kittel's exchange–inversion mechanism. By including both magnetic and structural contributions to the free e...

摘要:Abstract(#br)The outstanding electrical and mechanical properties of graphene make it very attractive for several applications, Nanoelectronics above all. However a reproducible and non destructive way to produce high quality, large-scale area, single layer graphene sheets i...

摘要:This paper introduces a non-equilibrium thermodynamic approach to describe vector magnetization in the presence of a magnetic moment current. The Larmor term present in the theory describes in this case how the magnetization dynamics can be a source of magnetic moment currents an...

摘要:Abstract(#br)We combine spin polarised density functional theory and thermodynamic mean field theory to describe the phase transitions of antiperovskite manganese nitrides. We find that the inclusion of the localized spin contribution to the entropy, evaluated through mean field ...
