Microstructure and magnetic domain structure of boron - enriched Nd 2 ( FeCo ) 14 B melt - spun ribbons
Heat treated melt-spun ribbons of (Nd La) Fe Co Nb B have been studied systematically by supercon-ducting quantum interference device (SQUID) magnetometry, conventional transmission electron microscopy (CTEM) and Lorentz transmission electron microscopy (LTEM). The sample's microstructure grew from an amorphous state through a partially crystallized state at 6503C, and "nally to a fully crystal...
متن کاملMagnetic properties and synthesis conditions of Nd2Fe23B3 melt-spun alloy
The formation of amorphous and crystalline state of the Nd2Fe23B3 alloy from melt-spun ribbon is presented. The synthesis conditions are investigated combining DSC, X-ray diffraction and thermomagnetic analysis. The thermomagnetic analysis is found to be very useful to optimize the synthesis process. Comparison of these results enables to discuss the thermal stability of both the amorphous and ...
متن کاملEffect of Post-Sintering Annealing Treatment on Magnetic Properties of Some Nd Fe b Based Magnets
Effects of post-sintering annealing treatment between 300 and 1000ºC for up to 8 hrs time periods followed by either furnace cooling (FC) or air-cooling (AC) on the hard magnetic properties of some Nd-Fe-B based sintered magnets was investigated. It was shown that the intrinsic coercivity (Hci), second quadrant demagnetization loop shape and thus the energy density (BH)max varied considerably a...
متن کاملMagnetic properties of Nd-Fe-B/α-Fe multi-layered thick film magnets
Nd-Fe-B/α-Fe multi-layered nanocomposite film-magnets were prepared from a rotating Nd2.6Fe14B/α-Fe composite target by the pulse laser deposition method with a NdYAG laser (λ=355 nm). The prepared film-magnets were composed of approximately 800 layers with the thickness of about several tens nanometre, and exhibited hard magnetic properties after annealing. The laser power for the ablation of ...
متن کاملModification of the Interface Nanostructure and Magnetic Properties in Nd-Fe-B Thin Films
The effects of Nd2Fe14B grain size and Nd coating on the coercivity in sputter-deposited Nd-Fe-B/Nd thin films have been investigated in order to gain an insight into the coercivity mechanism of Nd-Fe-B magnets. Highly textured Nd2Fe14B particles were grown successfully on the MgO(100) single-crystal substrate with the Mo underlayer. As the Nd-Fe-B layer thickness t NFB was decreased from 70 to...
