An investigation of the Consejo Superior de Investigaciones Científicas (CSIC) has designed an experiment for measuring the effect present in a Graphene structure deformation cause about electrons that flow through it. The irregularities in this material generate a similar effect which causes a magnetic field on electrons in the structure. The CSIC research has been published in the latest issue of the journal "nature physics".

The work is based on the effect Aharonov-Bohm, described in 1959, that allows to detect the presence of a magnetic field in a region of space without measuring directly on it. This effect predicts that the magnetic flux can be detected through observation of quantum interference of electrons traveling to her around, in a region where the field is null. "This experiment is strictly quantum nature and has no analog classic," says the head of the study, researcher at the CSIC in the Materials Science Institute that has participated in the work Maria Angeles Vozmediano.
