Resumen
Highly hexagonally ordered CoPd alloy nanowire arrays were synthesized through electrochemical deposition techniques into the nanopores of anodic alumina membranes used as templates. Two different electrolytes were used for this purpose, one with pH = 4.1 and the other with pH = 7. Under applying different electrodeposition parameters and by adjusting both, the current density and the electrolyte composition, it could be possible make to vary the composition of CoPd alloy nanowires in a wide range. Their composition and morphology were investigated by SEM and EDX. The magnetic properties of the nanowires array have been measured with a VSM as a function of the temperature, ranging from RT down to 50 K, for different CoPd alloy nanowires composition. Also, the temperature influence on the reversible-irreversible magnetization processes related with the magnetization reversal of the CoPd nanowires array has been analyzed by first order reversal curve (FORC) method. 12 6 4736 4743 FEDER Spanish MICINN FICyT [MAT2009-13108-C02-01, MAT2010-20798-C05-04, FC09-IB09-131, FC-10-COF10-04, BP07-075, BP10-035] FICyT [MAT2009-13108-C02-01, MAT2010-20798-C05-04, FC09-IB09-131, FC-10-COF10-04, BP07-075, BP10-035]
