Dr Oscar Cespedes

Profile

Our work is currently focused on spin transport and vibrational interactions in hybrid magneto-organic structures. However, we also do research in novel physical mechanisms in biomagnetism, protein dynamics and spectroscopy.

Research interests

My research interests cover a broad range of topics, including:
1.- Electron and spin dependent transport in carbon based materials, such as magnetic tunnel junctions with buckyballs(C60), and spintronics in graphene, carbon nanotubes and other organics.
2.- Magnetic field dependent transport in nanostructures, such as magnetic oxide nanoconstrictions (Fe3O4, NiOx, LSMO) and gas-stabilised break junctions.
3.- The electron/spin-phonon interaction in hybrid devices (probed by Raman, Brillouin light scattering and other techniques).
4.- Biomagnetism and novel mechanisms of interactions between RF/microwave magnetic fields and proteins.
5.- Exobiology and protein dynamics in conditions simulating those of other planets and/or outer space, including Raman microscopy at low temperatures (down to ~3 K) or under simulated microgravity using magnetic fields.
6.- The magnetic and optical properties of magnetic nanoparticles for device and biological applications.
