Switching On Magnetism in Ni-doped Graphene
E. J. G. Santos, A. Ayuela, S. B. Fagan +4
Magnetic properties of graphenic carbon nanostructures, relevant for future spintronic applications, depend crucially on doping and on the presence of defects. In this paper we stu…
Chemical doping-induced gap opening and spin polarization in graphene
I. Zanella S. Guerini, S. B. Fagan, J. Mendes Filho +1
By using first principles calculations we report a chemical doping induced gap in graphene. The structural and electronic properties of CrO interacting with graphene layer are…
Raman studies of polycrystalline CaCuTiO under high-pressure
D. Valim, A. G. Souza Filho, P. T. C. Freire +5
We report a Raman scattering study of polycrystalline CaCuTiO (CCTO) under pressure up to 5.32 GPa. The pressure dependence of several Raman modes was investigated.…
A Raman Investigation of PbZr0.94Ti0.06O3 Ceramics Under High-Pressures
A. G. Souza Filho, P. T. C. Freire, J. M. Sasaki +5
We have investigated the behavior of the PbZr(0.94}Ti(0.06)O3 Raman spectra as a function of Hydrostatic pressures. The new structural phases were identified based on previous work…
