Low computational cost semi-analytical magnetostatic model for magnetocaloric refrigeration systems

AIP Advances, 2018
The analysis of the active magnetic refrigeration (AMR) cycle for different waveforms of both the magnetic field and the velocity of the heat transfer fluid is an essential challenge in designing and implementing heating and cooling systems based on the ...

Collective magnetism in arrays of spinor Bose–Einstein condensates

New Journal of Physics, 2013
We elucidate dipolar magnetic interaction effects in spinor condensates at a low-background field. In particular, we show that arrays of ferromagnetic spinor Bose–Einstein condensates show a rich phase structure that is strongly influenced by the ...

Fast Multipole Method Applied to Volume Integral Equation Method [PDF]

Advances in Radio Science, 2005
The Volume Integral Equation Method (VIEM) has been used for the solution of three-dimensional non-linear magnetostatic field problems. The number of unknowns is minimal as only the magnetic material has to be discretized.
