The Co-Pt nanochessboard is a quasi-periodic, nanocomposite tiling of L10 and L12 magnetic phases that offers a novel structure for the investigation of exchange coupling, relevant to permanent magnet applications. Periodicity of the tiling is contro

Great progress has been made over the recent decades in the application of computational thermodynamics (Calphad) and theoretical methodologies (CVM) including so-called first principles approaches to modeling thermodynamic properties and the calcula

This work correlates the evolution of magnetic properties with microstructure for aging of Co–Pt alloys with compositions bracketing the A1→L1 0 +L1 2 eutectoid at about 60 at% Pt. The magnetic properties of Co 41.7 Pt 58.3 were observed to vary

The existence of an L10–L12 hybrid ordered phase for face-centered cubic (fcc) crystal symmetry was first theorized by William Shockley in 1938, but has not been verifiably observed to date. Ordered magnetic thin films of Fe38.5Pd61.5, the expected

The magnetic properties of bulk Co40.2Pt59.8 alloys were investigated during eutectoid decomposition to form the nano-chessboard structure. The nano-chessboard consists of nanorods of the magnetically hard L10 phase coherently embedded in a magnetica

We report the first detailed investigation into how exchange-coupled magnetic properties evolve during the formation of the Co-Pt L10 + L12 nanochessboards, which self-assemble by a pseudo-spinodal mechanism below the eutectoid isotherm. The maximum

Since the inception of matrix assisted pulsed laser evaporation (MAPLE), a large body of research has focused on the structure and property preservation of soft materials. Departing from this precedent, a variation of MAPLE to grow complex inorganic

The tetragonal lattice relaxation has been included in the thermodynamics of the fcc→L10ordering to produce a first-order character of the transition within the mean field description of the binary solution energetics. In view of growing interest i
