Uppsala University is a comprehensive research-intensive university with a strong international standing. Our mission is to pursue top-quality research and education and to interact constructively with society. Our most important assets are all the individuals whose curiosity and dedication make Uppsala University one of Sweden’s most exciting workplaces. Uppsala University has 46.000 students, 7.300 employees and a turnover of SEK 7.3 billion.

The research conducted at the Department of Physics and Astronomy encompasses a wide range of physics topics, distributed over ten divisions. The department is located in the Ångström laboratory and employs nearly 400 people, 125 of whom are doctoral students. It offers a broad physics curriculum to undergraduate and graduate students, participation in nationally and internationally leading projects for researchers, and opportunities for partnership with industry and various outreach activities.

Duties/Project description: The project concerns development of concepts and routes for obtaining active control of light using nanomagnetic architectures. We will use magnetism to form adaptive and reconfigurable flat optical devices using a novel class of magnets – two-dimensional lattices of single-domain nano-magnets – as a means to achieve control. Magneto-static interactions between the nano-magnets, will be used to obtain collective magnetic order and dynamics. Furthermore, the magnetic order can be controlled and reconfigured, using external stimuli such as magnetic fields, temperature or opto-magnetic effects. The nano-magnets can be used to obtain a phase grating for scattered light, since magneto-optical effects impose local changes on the polarization and phase of the optical wavefronts across the metasurface. Crucially, this grating structure is defined by the degree and nature of the magnetic order of the nano-magnets. We aim to elucidate the fundamentals of light scattering from magneto-optical metasurfaces, relating it to the magnetic order and dynamics. The project is a collaboration between experimental and theoretical groups in Uppsala.

You will participate in experimental work in nanofabrication of nanomagnetic arrays and characterize them with magneto-optical spectroscopy and scattering techniques. Furthermore, magnetic microscopy and magnetization dynamics studies will be included in the project.
