Recent results obtained for neutron-rich nuclei of mass A{approx}60-70 are presented together with the theoretical interpretation. The development of a new region of deformation approaching the neutron number N = 40 in Cr and Fe isotopes is discussed. A new effective interaction that considers the full fp shell model space for protons and the p{sub 3/2}, p{sub 1/2}, f{sub 5/2}, g{sub 9/2}, d{sub 5/2} orbitals for the neutrons allows to reproduce, for the first time, the different structure properties of these nuclei. The configuration of the calculated states suggests the development of a new island of inversion at N{approx}40. The perspectives offered by the forthcoming operation of the AGATA Demonstrator Array coupled to the magnetic spectrometer PRISMA at LNL are also discussed.
