摘要:Abstract(#br)Heat-treated Fe 42.7 Co 42.7 Zr 6.8− x Nb x B 6.8 Cu 1 ( x =0,1) alloys were studied. During nanocrystallization of these alloys, the ordered α′-FeCo phase is formed. Moreover, the magnetic susceptibility of the nanocrystalline alloys slightly depends on te...

摘要:Abstract(#br)The structure and low-field magnetic properties (i.e. the magnetic susceptibility and its disaccommodation) for the Fe 87 Zr 7 B 6 and Fe 86 Zr 7 B 6 Cu 1 alloys in the amorphous and nanocrystalline states are investigated. It was stated that the replacement of ...

摘要:Abstract(#br)It has been found that the replacement of 50% of Fe atoms by Co atoms in the Fe 83 Nb 3 B 13 Cu 1 amorphous alloy enhances the saturation magnetization. The presence of α-FeCo grains in the nanocrystalline Fe 41.5 Co 41.5 Nb 3 B 13 Cu 1 alloy leads to higher mag...

摘要:Abstract(#br)It was stated that the addition of Nb to the Fe 85.4 Zr 6.8 B 6.8 Cu 1 alloy leads to the decrease of the average hyperfine field at 57 Fe nuclei and Curie temperature of the amorphous materials. Moreover, the amount of the α-Fe phase in the nanocrystalline samp...

摘要:We report on sensing characteristics of an endlessly single mode silica fiber with microstructure squeezed by very large side-holes. An elliptical shape of the cladding holes results in high phase and group modal birefringence, equal respectively to B = 3.33 × 10−4...

摘要:We propose two designs of birefringent microstructured fibers assuring high geometrical birefringence in the visible range and low confinement losses. An increased birefringence level in the visible range is achieved by breaking the hexagonal symmetry of the structure and sh...

摘要:We demonstrate that adding a boron-doped inclusion in the core of a polarizing photoniccrystal fiber significantly increases its polarization bandwidth. We present thecharacteristics of two fabricated fibers, including spectral dependence of loss in bothpolarization modes and pol...
