EFFECT OF SURFACE CONDITIONS ON COERCIVITIES FOR Nd-Fe-B MAGNETS
نویسندگان
چکیده
Hysteresis loops of Nd-Fe-B magnets with different surface roughness are measured in order to investigate the surface effect on nucleation for magnetization reversal. The roughness affects both coercivity and the demagnetization process. This behavior is considered to be caused by the 90° domain wall pinning of the line scratches.

Effect 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 RAPIDLY QUENCHED (Nd, Pr)2 (Fe,Co)14B-TYPE ALLOYS
The coercivity Hc; of rapidly quenched Nd-Fe-B is linked to the multiphase structure of the alloys: high coercivities require the suppression of the &Nd solid solution and the exictence of the intergranular Nd-rich phase. In quarternary Pr-Fe-Co-B alloys H,i and the remanence J, depend in the same way on Co content as in the Nd-FeCo-B system. However, compared with rapidly quenched Nd-Co-B samp...
متن کاملRelation between domain wall motion and coercivity in Nd-Fe-B sintered magnets prepared in various conditions
For the study of the relationship between the domain wall motion (DWM) and the coercivity in the samples of Dy-free Nd-Fe-B sintered magnets, the DC susceptibility (χDC) in the initial magnetization from the thermally demagnetized state and the DWM in the partially demagnetized state after the full magnetization in 5T-pulse field were measured. In the high coercivity (μ0Hc) samples of μ0Hc=1.35...
متن کاملImpulse Magnetization of Nd-Fe-B Sintered Magnets for Sensors
Magnetization of large Nd-Fe-B sintered permanent magnets is still challenging. This type of permanent magnet is electrically conductive, so impulse magnetization causes a flow of eddy currents which prevent magnetization of the whole volume of the magnet. The paper deals with the impulse magnetization of sintered Nd-Fe-B permanent magnets and shows a method for the determination of suitable pa...

Isotropic Nd-Fe-B thick-film magnets have been prepared using a pulsed laser deposition (PLD) method with the control of laser energy density (LED) followed by post-annealing. The characteristics of the method are a high deposition rate up to several tens of microns per hour together with a reliability of magnetic properties due to the good transfer of composition from an Nd-Fe-B target to a fi...
