Coexistence of blocked, metamagnetic and canted ferrimagntic phases at high temperature in Co–Nd ferrite nanorods

• One-dimensional Co–Nd nanoferrite were prepared by co-precipitation method.
• Co–Nd ferrite nanorods exhibits magnetic blocking phase.
• It exhibits metamagnetic phase with the corresponding Morin transition temperature.
• It exhibits ferrimagnetic phase with the corresponding Neel temperature.

One-dimensional Co–Nd ferrite nanostructures were prepared by controlled co-precipitation method. Co–Nd ferrite nanorods exhibits different magnetic phases: blocking phase with the corresponding blocking temperature (TB) of about 350 K, metamagnetic phase with the corresponding Morin transition temperature (TM) of about 550 K and canted ferrimagntic phase with the corresponding Neel temperature (TN) of about 800 K. These novel magnetic one-dimensional structures can potentially be used in nanoelectronic devices, magnetic sensors, and flexible magnets.
