• Abstract

  In this project, we propose the purchase and installation of a helium liquefier, our objective being to ensure the supply of liquid helium to all of the users in the São Carlos region. The USP São Carlos Institute of Physics (IFSC) has a long tradition in cryogenic infrastructure, routinely having been able to furnish nitrogen and liquid helium to its users since the early 1970s. The IFSC…

• Abstract

  Continuous-Wave (CW) Electron Paramagnetic Resonance (EPR) has been widely used in structural studies of a variety of problems, inc1uding many interesting biologically relevant systems. It has contributed very significant1y to the characterization of metal binding sites in proteins, to the study of the dynamic structure of biomembranes and to the kinetics of several processes such as elec…

• Abstract

  In this work, antiferromagnetic interactions of polycrystalline samples of the multiferroic BiMn2O5, of doped polyanilines and of monocrystalline samples of the ludwigite Fe3O2BO3 will be studied through Electron Spin Resonance (ESR) technique. Simulations and fittings of the ESR spectra give detailed information about the local structure and the magnetic interactions present in those sys…
