We welcome September with the first seminar of the academic year. Here you can find all the information:
Title: An Ultrafast View on the Magnetization Dynamics of Van der Waals Materials
Author: Marcos H. D. Guimarães - Zernike Institute for Advanced Materials University of Groningen
Abstract: Van der Waals (vdW) magnets are ideal systems for the study of magnetism in low dimensions since they maintain their excellent magnetic properties down to the atomic limit. Because of their low dimensionality, these materials possess another exciting property, they are extremely sensitive to external stimuli, such as light and electric fields. For these reasons, vdW magnets are promising candidates for applications on atomically-thin circuits which are able to store data using their magnetization, and process and transmit information through electrical and optical means.
In this talk, I will introduce the field of magneto-optics in two-dimensional materials and show how we can use light to read magnetic information at the nanoscale. I will show examples on how the magnetization of vdW magnets can be manipulated using ultrashort (fs) laser pulses, and how their magnetization dynamics can be efficiently controlled by magnetic and electric fields.
Our studies illustrate the potential of vdW magnets for combining optics and magnetism, making them appealing for new opto-magnetic device architectures for future integrated photonic systems.
