Phases at the interface

Magnetic and superconducting phases at the LaAlO3–SrTiO3 interface

The formation of a metallic state at the interface of the bulk insulators LaAlO3 and SrTiO3 [1] has become a prototype for the reconstruction of electronic states in systems with artificially reduced dimensionality. This two-dimensional (2D) electronic system is affected by sizable electronic correlations which allow characterizing the extended interface electronic states as an electron liquid....

Composition at the interface between multicomponent nonequilibrium fluid phases.

The computation of mass transfer between two nonequilibrium phases requires interfacial composition. For a system with a total of M components, the assumption of local thermodynamic equilibrium provides only M equations while the number of unknown interfacial compositions is 2(M-1). In binary systems (M=2), the number of equations matches the number of unknowns and the interfacial composition i...

Refraction at the Interface of a Lossy Metamaterial

The refraction phenomenon at the interface of an ordinary material and a lossy metamaterial has been investigated. For oblique incidence on the lossy metamaterial, the planes of constant amplitude of the refracted wave are parallel to the interface and the plane of constant phases make a real angle with the interface (real refraction angle). The real refraction angle and hence, the real refract...

Magnetic and superconducting phases at the LaAlO3/SrTiO3 interface: The role ofinterfacial Ti 3d electrons

Metallurgical phases and their magnetism at the interface of nanoscale MgB2/Fe layered structures.

We report on the characterization of metallurgical phases and their magnetism at the interfaces of nanoscale MgB(2)/Fe layered structures. MgB(2)/(57)Fe multilayers with varying layer thicknesses were prepared by vacuum deposition and investigated, before and after annealing by electrical resistance measurements, x-ray diffraction and (57)Fe conversion-electron Mössbauer spectroscopy (CEMS) dow...
