Photoinduced Picosecond‐Scale Radial Current for Generating and Converting Spin Textures
Nanophotonics, Volume 15, Issue 7, 13 April 2026.A picosecond‐scale vector electrical current is generated and applied to generate and convert spin textures. Four target quasiparticle types with different topological states are generated with ultrafast speed (< 50 ps). Besides, the controlled transitions between these spin textures are achieved. ABSTRACT Magnetic skyrmions are topologically protected

Nonlinear conjugate gradient methods in micromagnetics
AIP Advances, 2017 Conjugate gradient methods for energy minimization in micromagnetics are compared. The comparison of analytic results with numerical simulation shows that standard conjugate gradient method may fail to produce correct results. A method that restricts the

Thermomagnetically patterned micromagnets [PDF]
Applied Physics Letters, 2010 Thermomagnetic patterning (TMP) of 4 μm thick high performance NdFeB hard magnetic films deposited on Si substrates has been achieved using single pulsed laser irradiation. Uniaxially magnetised chessboard and stripe patterns with lateral feature sizes in the range 50–100 μm were produced.
