Characteristics of Interior Permanent Magnet Synchronous Motor with Imperfect Magnets

IEEJ Journal of Industry Applications, 2014
This paper investigates the effect of demagnetization of the permanent magnets (PM) on the performance of interior permanent magnet motors. In order to remove the individual difference of the motors, several shapes of PMs are prepared, and the experiments are carried out with the same stator.

Laser‐Induced Ultrafast Magnetic Phase Transition in 2D Van Der Waals Antiferromagnetic Heterostructures

Advanced Science, EarlyView.
In this work, ultrafast laser‐induced spin transfer and spin relaxation dynamics in 2D van der Waals antiferromagnetic CrI3/CrGeTe3 heterostructures are investigated. Laser excitation is demonstrated to induce pronounced interlayer nonequilibrium spin dynamics and ultrafast magnetic moment reconstruction, driving a transition from an antiferromagnetic (
