Surface critical behavior of bcc binary alloys

Wetting phenomena in bcc binary alloys

The wetting behavior at the free (100) surface of a bcc binary alloy exhibiting a continuous order-disorder transition in the bulk is investigated theoretically, using a model equivalent to a bcc Ising antiferromagnet in an external magnetic field. Its salient feature is the generation of an effective ordering surface field , g1 6= 0, for certain symmetry-breaking surface orientations like (100...

Surface effects of ordering in binary alloys

This article reviews the most important achievements in the studies of the compositional (chemical) and magnetic ordering effects in the surface region of single-crystal binary alloys with different bulk structures. These alloys include the non-magnetic and magnetic concentrated substitutional binary systems which have a tendency to ordering (Au–Cu, Cu–Pt, Fe–Pt, Co–Fe, Fe–Ni, Al–Fe, Al–Ni, Pt–...

Monte Carlo studies of directional pair ordering in disordered binary and ternary ferromagnetic BCC crystalline alloys

Magnetic field annealing can be used to induce uniaxial magnetic anisotropy in ferromagnetic alloys, which is often desirable, for example, to reduce core losses in materials of interest for high frequency inductive components in power conversion applications. An understanding of the compositional dependence of the uniaxial induced anisotropy constant KU is important to develop materials for su...
