Soft magnetic properties of Fe-Co-Ni-Al-Cr-Si thin films were studied. As-deposited Fe-Co-Ni-Al-Cr-Si nano-grained thin films showing no magnetic anisotropy were subjected to field-annealing at different temperatures to induce magnetic anisotropy. Optimized magnetic and electrical properties of Fe-Co-Ni-Al-Cr-Si films annealed at 200 ◦C are saturation magnetization 9.13 × 105 A/m, coercivity 79...

co-fe films were electrodeposited on cu substrate from electrolytes with different co concentration  levels. x-ray diffraction (xrd) was used  to  investigate  the  films  crystal  structures. the  results  indicate that  if  the  co  concentration  is  less  that  the  fe  concentration,  the cubic  structure  appears  in  the  films, while  the  hexagonal  structure dominates when  the co  co...

the effect of length variation on the magnetic properties of nife alloy nanowires electrodeposited into the alumina template was investigated. the diameter (45±2.5 nm) and length (~ 1.9, 7.12, 8.3, 9.5 and 13.3 µm) of the nanowires were estimated from scanning electron microscopy images. energy dispersive spectroscopy results showed ni3fe7 composition of the alloy nanowires.  the magnetic prope...

We present an extension of the King et al. [1] model for the flickering of black hole accretion discs by taking proper account for the thermal properties of the disc. First we develop a one-dimensional, vertically averaged, one-zone model for an optically thick accretion disc and study the temporal evolution. This limits the current model to the so-called high/soft state, where the X-Ray spectr...

The structural and magnetic properties of rare-earth nanocomposite magnets of a (Nd,Dy)(Fe,Co,Nb,B)5.5 single layer and a (Nd,Dy)(Fe,Co,Nb,B)5.5/α-Fe multilayer prepared by sputtering and heat treatment have been investigated. Incomplete exchange coupling behaviour is observed in the Ti-buffered NdDyFeCoNbB + 40 wt%Fe single layer magnet. After annealing, the laminated nanostructure consisting ...

Soft-materials that respond to external stimuli are very useful for application in soft robotics, stretchable electronics, biomedical applications etc. Recent times have seen a surge research of magnetically activated polymers due their wide range material properties, and important features such as non-contact, fast non-invasive actuation. Furthermore, these ask Hard-magnetic particles, which c...
