Study of magnetization process in ordered Fe nanowire arrays

Fe polycrystalline nanowires were electrodeposited in nanoporous anodized alumina membranes. Their magnetic properties were studied at 10 K. The behavior of the isothermal remanence _Mr$M_{\mathrm{r}}$ and the demagnetization remanence _Md$M_{\mathrm{d}}$ was determined. The corresponding ΔM$\mathrm{\Delta }M$ plot revealed the character demagnetizing of the dominant interactions. A simple analysis suggests that curling is the reversal magnetization mode in these samples. The forms of the _Mrev(_Mirr)Hi$M_{\mathrm{rev}}(M_{\mathrm{irr}}{)}_{H_{\mathrm{i}}}$ curves were different from those encountered until now, and it seems that these forms are associated with the curling reversal mode.
