Structural and Magnetic Studies of Half-Metallic Heusler Alloy Or_2COSi Nanoparticle Synthesized by Mechanical-Alloying method

摘要

Heusler Alloy based Cr_2CoSi nanoparticles were synthesized by using ball milling. X-ray diffractions studies were used to characterize the crystal structure of Cr_2CoSi nanoparticles and magnetic properties were studied using VSM. XRD data analysis confirms the Heusler alloy phase showing the L2i structure. Magnetic properties are measured for synthesized samples having coercivity Hc= 389 Oe, with high saturation magnetization value Ms= 8.64 emu/g and remenance value Mr= 2.93 emu/g. Synthesized Heusler alloy Cr_2CoSi nanoparticles can be potential materials for use in Spin polarized based spin sensors, spin devices, magnetic sensors and transducer applications.
