CoxC nanorod magnets: Highly magnetocrystalline anisotropy with lower Curie temperature for potential applications

Magnetic CoxC nanorods with larger magnetocrystalline anisotropy of 5×105 J/m3 as well as larger coercivity and lower Curie temperature are introduced. The particles have an average diameter of 8 nm and shows three different magnetic behaviors. The sample shows ferromagnetism up to 400 K, superparamagnetism at temperature >400 K and
