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 S_inplane < S_perp for Ni2, Ni3 and S_inplane > S_perp for Ni6. The observed differences in the MHL are related to the nanowires lengths which determine different magnetic interactions between nanowires.
