Magnetic properties of nanocarbon

Our experimental results provide the evidence that ferromagnetic properties of polymerized fullerenes are of non-trivial origin. Comparison of magnetic measurements, impurity analysis and Raman spectroscopy proves that in certain cases the sample structure affects the magnetic ordering. We provide the explanation of the results obtained of fullerenes within the model of charged fullerenes, where the charge comes from various defects and impurities. It is important that the impurities do not have to be magnetic: even carbon impurity in the all-carbon fullerene network can act as a magnetic trigger.
