Magnetic Anisotropy in Ordered L10 type NiFe Alloy

Tight-binding study of the electronic and magnetic properties of an L10 ordered FeCu alloy

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. PACS numbers: 75.50.Rr, 7...

Domain-wall scattering in epitaxial FePd ordered alloy films with perpendicular magnetic anisotropy

Domain-wall scattering in a FePd-ordered alloy film with strong perpendicular magnetic anisotropy has been investigated using magnetoresistance measurements on a whole hysteresis loop and as a function of temperature. A strong correlation between the hysteretic behavior of the resistivity due to domain walls and the magnetization process is found. The data are well described by a spin-dependent...

In-plane/out-of-plane disorder influence on the magnetic anisotropy of Fe1-yMnyPt-L10 bulk alloy

Anisotropy of Interfaces in an Ordered Hcp Binary Alloy

A multiple-order-parameter mean eld theory of ordering on a binary hexagonal-close-packed (HCP) crystal structure is developed, and adapted to provide a continuum formulation that incorporates the underlying symmetries of the HCP crystal in both the bulk and gradient energy terms of the free energy. The work is an extension of the previous treatment by Braun et al. Phil. Trans. Roy. Soc. Lond. ...

Edge-modulated perpendicular magnetic anisotropy in [Co/Pd]n and L10- FePt thin film wires

Thickness modulation at the edges of nanostructured magnetic thin films is shown to have important effects on their perpendicular magnetic anisotropy. Thin film wires with tapered edges were made from [Co/Pd]20 multilayers or L10-FePt films using liftoff with a double-layer resist. The effect of edge taper on the reversal process was studied using magnetic force microscopy (MFM) and micromagnet...
