The geometrical constraints of the zeolite host structure allow for the formation of one-dimensional chains of highly uniaxially oriented molecules.<\/figcaption><\/figure>\n<p><strong>Resumo do projeto.<\/strong><br \/>\nSystems featuring large magnetoresistance (MR) at room temperature and in small magnetic fields are strongly sought-after due to their potential for magnetic field sensing and data storage. Usually, the magnetic properties of materials are exploited to achieve large MR. Recently, we have discovered an exceptionally large, room-temperature, small-field MR effect in 1D, non-magnetic systems of molecular wires self-assembled in a zeolite host crystal [R.N. Mahato, H. L\u00fclf, M.H. Siekman, S.P. Kersten, P.A. Bobbert, M.P. de Jong, L. De Cola and W.G. van der Wiel, Science 341, 257 (2013)]. This ultrahigh MR effect is ascribed to the dramatic consequence of spin blockade in 1D electron transport. In this project we will investigate this system more elaborately, in particular we will perform electron spin resonance (ESR) experiments. From electrically detected magnetic resonance (EDMR) measurements we hope to learn more about the character of the charge carriers, the molecular orbitals involved, and we may be able to realize quantum coherent oscillations.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Vaga para realizar doutorado em projeto de resson\u00e2ncia magn\u00e9tica detectada eletricamente (RMDE) de fios moleculares, com orienta\u00e7\u00e3o do professor Carlos Graeff\u00a0(Unesp &#8211; campus de Bauru).
