The existence of multiple ferroic orders in the same material and the coupling between them have been known for decades. However, these phenomena have mostly remained the theoretical domain owing to the fact that in single-phase materials such couplings are rare and weak. This situation has changed dramatically recently for at least two reasons: first, advances in materials fabrication have mad...

An overview of developments in materials theory is presented, with an emphasis on first-principles calculations. Examples are given from the fields of heterojunction interfaces and point defects in semiconductors. Predictive theories of materials are shown to be increasingly important for understanding but also designing materials and structures. © 2003 American Vacuum Society. @DOI: 10.1116/1....

The aim of this paper is to characterize welding of AISI 310 austenitic stainless steel to Inconel 657 for use in oil-refining industries. The welds were produced using four types of filler materials; nickel-based alloys designated as Inconel 82, A, 617, and 310 SS. The interfaces and heat-affected zones were characterized by optical and scanning electron microscopy. Interfaces on the two sides...

Computational micromechanical studies of the effect of nanostructuring and nanoengineering of interfaces, phase and grain boundaries of materials on the mechanical properties and strength of materials and the potential of interface nanostructuring to enhance the materials properties are reviewed. Several groups of materials (composites, nanocomposites, nanocrystalline metals, wood) are consider...

Ferromagnetic Josephson junctions exhibit fascinating physics and the potential for applications in superconducting logic memory. The a demonstrated memory prototype contain magnetic spin-valve structure with Ni as fixed layer NiFe (Permalloy) free layer. However, exhibits poor supercurrent transmission, which limits efficiency of junction. We have previously shown that transmission through Cu/...

Superconductivity in topological materials has drawn a significant interest of the scientific community as these provide hint existence Majorana fermions conceived from quantized thermal conductivity, zero-biased conduction peak and anomalous Josephson effect. In this review, we make systematic study recent advances field superconductivity. The article comprises both bulk systems well heterostr...

The present work deals with hierarchical composites in three dimensions, whose constituents behave as non-aging linear viscoelastic materials. We model the influence that imperfect interfaces have on macroscopic effective response of these structures. As an initial approach, problem two bodies adhesion is studied and particular case soft interface at zero-order considered. deduce integral form ...
