Group of Optoelectronics and Spintronics
Welcome to the Homepage of Research Group of Optoelectronics and Spintronics (RGOS) of the Federal Rural University of Pernambuco. The RGOS is supervised by Prof. José Holanda da Silva Júnior (known as Prof. José Holanda). The group was founded in 2022 and so far has made the following discoveries: 1 - first observation of the magnetic interfacial effect between a paramagnetic/non-collinear antiferromagnetic bilayer; 2 - showed for the first time the spin current hermiticity; 3 - defined the states of magnetization and demagnetization of magneto-optical interactions.

Highlights
2024 - Master's student develops new technique for MicroElectroMechanical systems (MEMs)
Luana Maria Carvalho da Silva Hildever created the new technique and is working to broaden the horizons of her research. His master's project supported by FACEPE is entitled Producing Sensors with MicroElectroMechanical Systems (MEMs) for Telecommunications Applications, that is, the technique is something that consolidates his research and also expands the research carried out in the Optoelectronics and Spintronics Group and Laboratory, which (Group and Laboratory) are the responsibility of Professor José Holanda da Silva Júnior.
Selected for the 2024 European School on Magnetism (ESM)
ESM 2024 will be held from 27 August to 6 September 2024, in mixed format, both onsite in York, UK, and online. The topic is Magnetism for energy-efficient devices. This is one of the most prestigious magnetism schools in the world, congratulations Maria Clara Gonçalves Santos.
