摘要
Fe polycrystalline nanowires were electrodeposited in nanoporous anodized alumina membranes. Their magnetic properties were studied at 10 K. The behavior of the isothermal remanence M-r and the demagnetization remanence M-d was determined. The corresponding 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 M-rev(M-irr)(Hi) curves were different from those encountered until now, and it seems that these forms are associated with the curling reversal mode. (c) 2007 Elsevier B.V.
