FeCo-BASED SOFT MAGNETIC NANOCRYSTALLINE ALLOYS
The influence of microstructure on the magnetic properties is studied in series of of FeCoNbB, FeCoZrB and FeCoMoBCu amorphous and nanocrystalline alloys with different amount of crystalline phase.V arious thermomagnetic treatments have been used in order to tailor the soft magnetic characteristics of these alloys for potential applications. We report on a beneficial effect of both longitudinal...
متن کاملNear equiatomic FeCo alloys: constitution, mechanical and magnetic properties
Alloys based on the near-equiatomic FeCo offer exceptional magnetic properties. The equiatomic alloy was ‘invented’ in 1929, it offers a saturation hardly lower than that of the maximum obtained for Fe-0.35Co, with higher permeability and a lower coercivity than the latter. However, this alloy remained without industrial application, mainly because of its extreme brittleness. Only with the addi...

متن کاملEvolution of strength and coercivity during annealing of FeCo based alloys
Iron-cobalt alloys are used as soft-magnetic materials in circumstances where a high magnetic saturation is important. There is confusion in the literature about the cause of an observed discontinuity in the variation of strength and coercivity as a function of the temperature at which cold-rolled Fe-Co alloys are annealed. It is shown here using calculations based on published data, that the v...
متن کاملThermoelectricity and disorder of FeCo/MgO/FeCo magnetic tunnel junctions
We compute the thermoelectric transport parameterized by the Seebeck coefficient and thermal/electric conductance of random-alloy FeCo/MgO/FeCo(001) magnetic tunnel junctions (MTJs) from first principles using a generalized Landauer-Büttiker formalism. The thermopower is found to be typically smaller than those of Fe/MgO/Fe(001) MTJs. The (magneto-)Seebeck effect is sensitive to the details of ...
