Abstract :
The dipolar interaction fields in an electrochemically deposited Ni nanowires (samples labeled Ni2, Ni3, Ni6) are characterized using the ferromagnetic resonance. The major hysteresis loops (MHL) are measured using vibrating sample magnetometer with the applied field perpendicular and parallel to the membrane plane. It is observed that the MHL squareness, S ,for the in plane and perpendicular configurations is Sinplane < Sperp for Ni2, Ni3 and Sinplane > Sperp for Ni6. The observed differences in the MHL are related to the nanowires lengths which determine different magnetic interactions between nanowires.
