چکیده

We have calculated the electronic structure of the tetragonal L10 ordered FeCu by solving self-consistently a tight-binding Hamiltonian for s, p and d electrons. We have found by total energy calculation that this structure is ferromagnetic. In addition, we have determined that the equilibrium ratio between the interlayer and the intralayer lattice parameters is 0.947.

Tight- binding study of electronic band structure of anisotropic honeycomb lattice

 The two-dimensional structure of graphene, consisting of an isotropic hexagonal lattice of carbon atoms, shows fascinating electronic properties, such as a gapless energy band and Dirac fermion behavior of electrons at fermi surface. Anisotropy can be induced in this structure by electrochemical pressure. In this article, by using tight-binding method, we review anisotropy effects in the elect...

Magnetic properties of X-Pt (X=Fe,Co,Ni) alloy systems

We have studied the electronic and magnetic properties of Fe-Pt, CoPt and Ni-Pt alloy systems in ordered and disordered phases. The influence of various exchange-correlation functionals on values of equilibrium lattice parameters and magnetic moments in ordered Fe-Pt, Co-Pt and Ni-Pt alloys have been studied using linearized muffin-tin orbital method. The electronic structure calculations for t...

Structural, magnetic, and electronic properties of Fe/Au monatomic multilayers.

An Fe/Au monatomic multilayer, consisting of alternating single Fe and Au layers, has been studied by means of the self-consistent full-potential linearized augmented plane wave method. We show by total energy minimization that this artificial thin film is in the tetragonal L10 ordered structure with the ratio of the interlayer spacing to the intralayer lattice constant at 0.865. In this config...

Magneto-optical spectra of long range chemically ordered FePd(001) alloy films

The occurrence of chemical ordering can have a dramatic influence on structural, electronic, and magnetic properties in many materials systems. Examples of recent interest are binary metallic alloy systems such as CoPt, FePt, and FeAu, where strong interdependencies between magnetic and magneto-optical properties and the degree of long range chemical ordering have been observed. Near the equiat...

In this communication we present a study of the electronic structure of partially disordered bulk and (100) thin film of quaternary pseudo-Heusler alloy Co2Fe0.4Cr0.6Al in the L21 phase using the Augmented Space recursion (ASR) in a scalar-relativistic tight binding linear muffin-tin orbitals (TB-LMTO) basis. We study the orbital resolved magnetic moment contributions of the constituents of the...
