Improvements of single sheet testers for measurement of 2-D magnetic properties up to high flux density [PDF]
, 1999 Due to structural limitation, the currently proposed apparatus based on a single sheet tester (SST) cannot measure magnetic properties along arbitrary directions (so-called 2-D magnetic properties) of silicon steel at high flux densities.

Advanced Functional Materials, EarlyView.OEG‐functionalized Y6‐derived acceptors induce thermally driven vertical phase separation, enabling pseudo‐planar heterojunction organic photodetectors. The resulting PM6:YTEG‐4F and PM6:YTEG‐4Cl organic photodetectors suppress dark current density by approximately 260‐fold and 210‐fold, respectively, while maintaining efficient photoresponse ...

2020 IEEE Energy Conversion Congress and Exposition (ECCE), 2020 Permanent magnet synchronous machines (PMSMs) performance is highly dependent on the Permanent Magnets (PMs) temperature. Knowledge of the PMs temperature is therefore of great importance both for control and monitoring purposes. An increase in the PM temperature during motor operation, decreases PMs magnetic flux strength and consequently the PMSM ...
