Electro Magnetism & Spintronics

The BINA Electro Magnetism researchers study novel magnetic phenomena and develop advanced spintronic devices using magnetic nanoparticles, magnetic thin films, and heterostructures. They study the interplay of magnetism and superconductivity and explore the emergence of magnetic phenomena in strongly correlated materials and at various interfaces. The researchers use nanofabrication facilities to develop novel magnetic sensors and memory devices with immense potential impact on vital technologies. A significant effort of the researchers is related to medicine, where attempts are made to develop devices and procedures that harness magnetism for diagnosis and treatment.

  • Nano-scale crystallization phenomena

    Our group is developing approaches that utilize nano-scale systems for studies of crystallization phenomena and mechanisms that determine the morphologies of crystals. Insight from this research can lead to very useful technological applications, as understanding crystal growth mechanisms will allow us to better control crystalline products of chemical synthesis. This view is inspired by treating nano-crystals as “embryonic” stages of crystal growth. In a sense, every crystal begins its evolution as a nano-crystal. The huge advantage in studies that follow this perspective is in our ability to utilize extremely powerful electron microscopy methods, including a novel technique that allows us to perform high resolution electron microscopy directly in liquid solutions. In this way we can retrieve details of the crystal structure and overall shape at remarkable resolution, during the crystal’s initial formation. These details are often hidden in bulk crystals, unidentifiable by X-ray crystallography, yet critical for understanding of the mechanisms by which crystals grow.

  • The Lab for Quantum Imaging

    The lab is focused on using quantum sensors for imaging various physical properties at the nanoscale. The two main sensors are a sensor for electric potentials based on carbon nanotubes and a sensor for magnetic fields based on Nitrogen Vacancies (NV) in diamonds. Those sensors have a unique combination of small dimensions and extremely high sensitivity,
    allowing us to use them for sensing minute fields at the nanoscale. The current projects focus on combining these two unique sensors to overcome many of the limitations of each system. For example, read the NV center’s quantum state using a charge detector made of a carbon nanotube. A second example is using the NV center for probing the electron state on the carbon nanotube with quantum coherence. These projects will pave the way for a quantum imaging technique that probes the quantum nature of a system at the nanoscale.
