Abstract: In this paper, the dependence of magnetic transitions temperatures of nanoporous materials on pore geometric characteristics (volume and shape) have been studied in the framework of the cohesive energy-based model in the case of pure nanoporous nickel and cobalt. Pore geometric characteristics have been taken into account using two parameters: its effective diameter and shape coefficient of a pore which characterizes the degree of deviation of its shape from the spherical one. The estimates allow expecting the possibility to obtain nanoporous macroscopic objects of ferromagnetic materials with a reduced Curie temperature which value also decreases with “complicating” the pore shape.
Keywords: nanostructuring, porous materials, ferromagnetism, magnetic transitions, Curie temperature.
