An international team led by researchers at Princeton University has uncovered a new class of magnet that exhibits novel quantum effects at room temperature. Quantum magnets are promising pl...
On behalf of the International Organising Committee it is a great pleasure for us to invite you to the 25th International Conference on Magnet Technology in 2017 from August 27 to September 1 in Amste...
Optimal current waveforms for brushless permanent magnet motors
Permanent magnetic electric magnetic current waveform emf waveform voltage current limiting eddy current loss model
2015/8/7
In this paper we give energy-optimal excitation current waveforms for a permanent magnet synchronous motor that result in a desired average torque. Our formulation generalizes previous work by includi...
Titanium and gold are usually not magnetic and cannot be magnets – unless you combine them just so.Scientists at Rice University did so and discovered what is a first of its kind: an itinerant antifer...
Spin current and polarization reversal through a single-molecule magnet with ferromagnetic electrodes
Spin current polarization reversal single-molecule magnet ferromagnetic electrodes
2012/2/27
We theoretically study the spin-polarized transport through a single-molecule magnet, which is weakly coupled to ferromagnetic leads, by means of the rate-equation approach. We consider both the ferro...
