Neoclassical tearing mode stabilization by electron cyclotron current drive in EAST tokamak experiments

Nuclear Fusion
The stabilization of the m / n = 2/1 neoclassical tearing mode (NTM) by electron cyclotron current drive (ECCD) has been carried out in EAST H-mode discharges, where m / n is the poloidal/toroidal mode number.

Optimal Control Drives Ultrafast and Energy‐Efficient Magnetization Switching in Van der Waals Magnets

Advanced Materials, EarlyView.
ABSTRACT The accelerating expansion of data‐centric technologies is sharply increasing the energy burden of information storage, placing unprecedented pressure on the efficiency of magnetic switching. Conventional field‐driven reversal, once the foundation of magnetic memory, has become impractical in modern architectures due to its high energy cost ...

Effect of n = 2 externally-applied magnetic perturbations on fast-ion confinement in MAST-U

Nuclear Fusion
Experiments with externally-applied magnetic perturbations (MPs) have been carried out in MAST-U to study the effect on the fast-ion distribution. Scans performed of the current applied in the coils, the toroidal phase offset between the currents in the ...

Moiré‐Induced Symmetry Breaking of Charge Order in van der Waals Heterostructures

Advanced Materials, EarlyView.
A uniaxial moiré potential in misfit (MS)1+δTaS2 heterostructures selectively reshape charge order: the embedded 1H‐TaS2 layer hosts an incommensurate charge‐density wave, fragmented into nanometer domains and stripped of threefold symmetry. Superconductivity, however, remains uniform and fully gapped, revealing heterosymmetry stacking as a selective ...

Magnetic resonant and non-resonant investigations of LiLnF4 (Ln = Y, Tm) powders [PDF]

, 1998
The properties of dielectric powders of the Van Vleck paramagnet LiTmF4 and its diamagnetic analogue LiYF4 have been investigated by both resonant methods (EPR, NMR, and the mass-spectroscopy) and non-resonant ones (conductometry and magnetization ...

Side‐Chain‐Induced Interlayer Slipping in Metalloporphyrin COFs Enables Microenvironment and Spin‐State Regulation for Photocatalytic CO2 Reduction

Advanced Materials, EarlyView.
Alkoxy chain length drives a continuous transition from eclipsed AA to a serrated, slipped AA* configuration over Co‐porphyrin COFs. A moderate slip both contracts the pore channel to enrich CO2 and suppress hydrogen evolution, and enhances collective high‐spin of Co sites, which delivers a record CO production rate with high selectivity.
