Abstract The project is mainly focused towards the synthesis of new nanostructured magnetic materials prepared by electrochemical techniques: Non-cylindrical nanowires and heterogeneous composition Fe/Ni or Fe/Ni/Co nanowires. An important aspect refers toresearch into magnetic phenomena occurring on these non-homogenous nanowires because these systems allow us to introduce energy barriers along the wires playing with bottle necks/bellies or harder magnetic materials along the wires. The project is ambitious from the point of view of fundamental physics as introduce a new model for the study of magnetization reversal mechanisms or tunnelling effect on macroscopic objects. It also can contribute to the technological field concerning new magnets with a tuneable coercive field, magnetic field sensors or thermal-induced recording media. We can make use of the standard homogeneous wires, needed to carry out the systematic study of heterogeneous nanowires, to solve new questions as finite-size effects on fundamental magnetic parameters above room temperature, like coercivity and ordering temperature. The project aspires to extend our previous studies on Ni homogeneous nanowires, in a range of temperatures not covered until present, up to above the Curie temperature (TC) in Co and Fe nanowires. | |
