Picosecond evolution of an induced metallic state under infinitesimal optical doping in NdNiO3
NdNiO3 is a rare-earth nickelate where competing interactions yield a thermally induced metal–insulator transition accompanied by simultaneous structural and magnetic transitions. In recent years, fem...
Spin-wave-driven motion of a domain wall in a compensated ferrimagnet nanostripe
We propose a micromagnetic model of thin films of rare-earth iron garnets (REIGs), and we apply it to simulate the spin-wave (SW)-driven motion of domain walls (DWs) in REIG nanostripes at the compens...
