摘要：

Networks of Py (Ni81Fe19) and Fe have been fabricated by sputtering onto nanopored alumina membranes with various pore sizes. A large enhancement of coercivity, up to two orders of magnitude, has been observed. In contrast to those in uniform films, magnetoresistance (MR) measurements show the suppression of MR anisotropy. These unusual behaviors originate from the nanostructure of the networks.
