An Efficient Solver for Finite Element-based Constrained Transport in 3D Magnetohydrodynamics Applied to Magnetic Confinement Fusion
Golo A. Wimmer, Konstantin Lipnikov, Ben S. Southworth +1
We present an efficient solver framework for the stiff magnetic wave coupling arising in resistive magnetohydrodynamics (MHD) on realistic tokamak geometries. The approach builds o…
Observation of giant nonvolatile magneto-thermal switching in superconductor-ferromagnet hybrids
Yui Sakamoto, Fuyuki Ando, Keigo Ito +6
Magneto-thermal switch is a crucial thermal component which enables heat transfer control by the application of an external magnetic field. Recently, a nonvolatile behavior in magn…
Observation of orbital-angular-momentum-driven temperature modulation via the spin Peltier effect
Sang J. Park, Tsuneyoshi Kan, Takamasa Hirai +1
Angular-momentum transport provides a pathway for controlling energy flow in solids beyond conventional charge-based mechanisms. While spin currents are known to mediate spin-calor…
Revealing nonvolatile behaviors in magneto-thermal switching using microstructure-controlled superconducting composites
Keigo Ito, Yui Sakamoto, Hossein Sepehri-Amin +12
Thermal conductivity in a conductor changes by the application of an external magnetic field, which functions as a magneto-thermal switch. For superconductors, a large magneto-ther…
Trans-scale spin Seebeck effect in nanostructured bulk composites based on magnetic insulator
