Magnetic skyrmions: Nanoscale chiral particles for future information technologies? – seminar


The Environmental Seminar on Solid State Physics as well as Seminar of the AGH UST Academic Centre for Materials and Nanotechnologies will be held on 5th December 2018, at 9.00 am.

A lecture titled “Magnetic skyrmions: Nanoscale chiral particles for future information technologies?” will be given by PhD Joo-Von Kim from Centre for Nanoscience and Nanotechnologies, Université Paris-Saclay, France.

Venue: Academic Centre for Materials and Nanotechnology AGH UST (Kawiory 30 Street, building D-16, auditorium room 1.02A)

An abstract of the lecture

Chiral symmetry breaking appears in many facets of the natural world, where phenomena related to left- and right-handedness can be distinct from one another. In magnetic systems, chiral interactions can stabilise certain spin configurations with intriguing properties. A prominent example are magnetic skyrmions, which represent nanometre-scale whirls of magnetic moments that appear in nanometre-thick ferromagnetic layers. In this talk, I will give an overview of the present research on skyrmions and the materials systems in which they have been observed. I will describe some aspects of their dynamics, which is strongly nonlinear and can exhibit processes such as spontaneous particle-antiparticle generation. Finally, I will discuss some perspectives for applications in information technologies, such as information storage, probabilistic computing and reservoir computing.
