We provide evidence that proton irradiation of energy 2.25 MeV on highly oriented pyrolytic graphite samples triggers ferro- or ferrimagnetism. Measurements performed with a superconducting quantum interferometer device and magnetic force microscopy reveal that the magnetic ordering is stable at room temperature.

The spin dynamics of the ferromagnetic pinned layer of ferro-antiferromagnetic coupled NiFe/MnNi bilayers is investigated in a broad frequency range (30 MHz-6 GHz). A phenomenological model based on the Landau-Lifshitz equation for the complex permeability of the F/AF bilayer is proposed. The experimental results are compared to theoretical predictions.

The present article analyzes aspects of the intellectual trajectory of Maria Cecília Ferro Donnangelo and her principal works. The text emphasizes the innovating and pioneer role her work played in the first moments of social sciences in the field of health in the mid sixties, occurring just together with changes in medical education and medical practice in Brazil.
