The high cost of CoFe alloys has prevented their widespread use regardless promising properties such as magnetisation, Curie temperature, soft magnetic materials for temperature applications. Here, it is shown that AlMn can be used to create a CoFeMn0.5Alx alloy, which reduced Co content but comparable alloys, therefore providing more economical alternative pure magnets.

Feature Extraction, also known as Multidimensional Scaling, is a basic primitive associated with indexing, clustering, nearest neighbor searching and visualization. We consider the problem of feature extraction when the data-points are complex and the distance evaluation function is very expensive to evaluate. Examples of expensive distance evaluations include those for computing the Hausdorff ...

cofe/cu multilayer nanowires were electrodeposited into anodic aluminum oxide templates prepared by a two-step mild anodization method, using the single-bath technique. nanowires with 30 nm diameter and the definite lengths were obtained. the effect of cofe layers thickness and annealing on the magnetic behavior of the multilayer nanowires was investigated. the layers thickness was controlled t...

We report a discovery that self-assembled perovskite-spinel nanostructures can be controlled simply by selecting single-crystal substrates with different orientations. In a model BiFeO(3)-CoFe(2)O(4) system, a (001) substrate results in rectangular-shaped CoFe(2)O(4) nanopillars in a BiFeO(3) matrix; in contrast, a (111) substrate leads to triangular-shaped BiFeO(3) nanopillars in a CoFe(2)O(4)...

The microwave magnetoresistance of CoFe/Cu/CoFe/FeMn spin valves and CoFe/Cu/CoFe three-layer nanostructures with high has been studied. transmission reflection coefficients were measured at the frequency range from 26 to 38 GHz in magnetic fields up 12 kOe. It is shown that dependences coefficient are not symmetric respect H = 0 axis, as well magnetoresistance. established relative changes 1.5...

A molecular dynamics method has been used to study the formation of dislocations during the vapor deposition of NiFe/Au/NiFe/Au and CoFe/NiFe/CoFe/Cu multilayers. We observed the direct nucleation of misfit dislocations (with zero critical thickness) at (111) interfaces in the NiFe/Au/NiFe/Au system. Both the dislocation configuration and density observed in the simulations were similar to thos...

Isotropic magnetic materials with high resonant frequencies are useful for applications in microwave devices. Undoped CoFe thin films, as common soft magnetic materials with high saturation magnetization, show isotropic characteristics but no high frequency response. Here, we use ferrite doped CoFe thin film to realize a resonant frequency higher than 4.5 GHz at all orientations. The exchange c...

CoFeCu nanowires were deposited by pulsed electrodeposition technique into the porous alumina templates by a two-step mild anodization technique, using the single-bath method. The electrodeposition was performed in a constant electrolyte while Cu constant was controlled by electrodeposition current. The electrodeposition current was 3.5, 4.25, 5 and 6 mA. The effect of electrodeposition current...

CoFe–Cu granular films with ferromagnetic content ranging from 0.10 to 0.33 by volume were prepared by radio frequency sputtering. As-cast samples were rapidly annealed at various temperatures up to 750 °C to promote the segregation of CoFe particles within the metallic matrix. Magnetic and transport properties suggested that this family of samples may be classified into three groups: ~i! below...
