Improving magnet designs with high and low field regions
R. Bjørk, C. R. H. Bahl, A. Smith +1
A general scheme for increasing the difference in magnetic flux density between a high and a low magnetic field region by removing unnecessary magnet material is presented. This is…
Review and comparison of magnet designs for magnetic refrigeration
R. Bjørk, C. R. H. Bahl, A. Smith +1
One of the key issues in magnetic refrigeration is generating the magnetic field that the magnetocaloric material must be subjected to. The magnet constitutes a major part of the e…
Strain in the mesoscale kinetic Monte Carlo model for sintering
R. Bjørk, H. L. Frandsen, V. Tikare +2
Shrinkage strains measured from microstructural simulations using the mesoscale kinetic Monte Carlo (kMC) model for solid state sintering are discussed. This model represents the m…
Optimization and improvement of Halbach cylinder design
R. Bjørk, C. R. H. Bahl, A. Smith +1
In this paper we describe the results of a parameter survey of a 16 segmented Halbach cylinder in three dimensions in which the parameters internal radius, $r_{\mathrm{\scriptsize{…
Analysis of the magnetic field, force, and torque for two-dimensional Halbach cylinders
R. Bjørk, C. R. H. Bahl, A. Smith +1
The Halbach cylinder is a construction of permanent magnets used in applications such as nuclear magnetic resonance apparatus, accelerator magnets and magnetic cooling devices. In…
Visible light enhanced field effect at LaAlO3/SrTiO3 interface
Y. Lei, Y. Z. Chen, Y. W. Xie +8
Electrical field and light-illumination have been two most widely used stimuli in tuning the conductivity of semiconductor devices. Via capacitive effect electrical field modifies…
