value of Ni–Fe NWs in the alumina template is higher than that of the Ni sample and bulk Ni, also the Curie temperature of the Ni–Fe sample (790 K) is higher than that of the Ni sample one or bulk Ni.

heights is presented. The structural properties of PA/Ni and PA/Ni–Fe NWs, as well as the temperature dependence of the specific magnetization of these nanocomposites are investigated and discussed.
Experimental
Preparation of porousaluminatemplate
The preparation technique and the thickness of the PA
that of the Ni sample and bulk Ni, and is equal to 790 K, which is rather high. Note, that this value is less than the Tc of bulk Fe (1040 K) and Py (823 K) [47].
Conclusion
Arrays of compact Ni–Fe NWs with high aspect ratio (about 500) and diameters of 50 nm have been fabricated using a porousalumina
