The researchers whose trusted networks rank it highest, strongest advocate first. Every researcher gets a different order.

Magnetic texture based magnonics (2020, background): “Ferromagnetic nanodots can sustain a magnetic vortex state with a magnetic vortex core at the center, which can be imaged by magnetic force microscopy [424], for example in Fig.”
Opportunities at the Frontiers of Spintronics (2015, background): “A particularly interesting case is given by magnetic vortex singularities that form in soft-magnetic disks [158].”
Nanostructured surfaces: challenges and frontiers in nanotechnology (2004, positive): “This spot represents a flux core, i.e. a singularity of the vortex state in the permalloy dot, which was directly observed only recently (Schneider et al 2000, Shinjo et al 2000).”
The 2017 Magnetism Roadmap (2017, methodology): “Transmission electron microscopy with Lorentz imaging (Lorentz-TEM) of magnetic order [6], magnetic force microscopy (MFM) [7], secondary electron microscopy with polarization analysis (SEMPA) [8], photoemission electron microscopy (PEEM) [9], spin-polarized scanning tunneling microscopy (spin-STM) ”
Domain wall nanoelectronics (2012, background): “Vortices are frequently observed in ferromagnetic nanodots (Shinjo et al., 2000).”
Skyrmions in magnetic multilayers (2017, background): “4 spin textures, but they are only stabilized in geometrically confined magnetic nanostructures such as nanodisks and therefore immobile simply because of their confinement [2, 28].”
