Abstract

The Co3O4 nanowires have been successfully synthesized via modified template method. The as-prepared products have been characterized by EDS, TEM and HRTEM analysis. The magnetic behavior of it is investigated by a magnetic property measurement system. The nanowires exhibit some novel magnetic properties, which are different from its bulk material. The temperature dependence curves of magnetization in zero-field-cooling and field-cooling exhibit two peaks of antiferromagnetic at blocking temperature of ∼23 K and ∼31 K, respectively. The field dependent M(H) curves of the Co3O4 nanowires at T = 5 and 300 K both exhibit PM properties. Moreover, the diameter of nanowires is hence determined according to the finite size effect as approximately 7–11 nm, in consistent with the characterizations by HRTEM.
