Education:

  • 2015 Ph.D., University of Grenoble-Alpes, Grenoble, France
  • 2012 M.S., University Joseph Fourier, Grenoble, France
  • 2010 B.S., University Babeș-Bolyai, Cluj-Napoca, Romania

Research Interests:

  • Nanomagnetism
  • Magnetic metamaterials, especially Artificial Spin Ice Systems
  • Optical and magneto-optical metamaterials (metaoptics)
  • Classical frustrated spin models
  • Polarimetry and optical sensing

Dr. Chioar’s research group focuses on studying magnetic and optical metamaterials, both from a fundamental science standpoint and for potential applications in computing and sensing technologies. These nanoarchitectures offer a bountiful playground to design, visualize, control, and harness collective many-body phenomena at the forefront of nanomagnetism and nanooptics. The research employs various magnetic and optical characterization techniques and can also be complemented by numerical/theoretical undertakings. Current research projects focus on artificial spin ice systems and the investigation of new magneto-optical metamaterial designs.
