Motivated to predict the properties of new material belonging to the 7000 aluminum alloys (7000-Al-alloy), in this contribution, we develop a combined model based on the artificial neural network approaches to predict the class of the Al-alloy and co

In this work, we investigate the scattering phenomena at the inhomogeneous boundary of a magnetic interface in two-dimensional (2D)-triangular ferromagnetic waveguide. We especially examine two ferromagnetic interfaces, named heavy and superheavy sol

We present a theoretical model to compute the localized electronic states at the surface of an hexagonal compact packing (hcp) structures. The system under study is assimilated to a surface layer that ends a 3D semi-infinite hcp system, in [100] dire

We illustrate in this contribution the determination of the magnetic conductance across a nanocontact region defined by an isolated defect region joined between two mono-atomic leads ferromagnetically ordered. The system is described by the Heisenber
