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 systems. (AU)
