Doctorant•Imagerie et dynamique en magnetisme - IDMAG

Sujit Panigrahy étudie la dynamique de skyrmions magnétiques dans des films antiferromagnétiques synthétiques. Grâce à la microscopie à force magnétique, il étudie leur morphology et observe leur déplacement dans des pistes, induit par des impulsions de courant électrique.


Sujit Panigrahy studies the dynamics of magnetic skyrmions in synthetic antiferromagnetic films. Using magnetic force microscopy, he characterizes their morphology and observe their motion in nanotracks, induced by electrical current pulses.
