Abstract

The authors report room temperature ferromagnetism in La _0.5Sr_0.5Ti_0.985Co_c.015O _3-δ nanoparticles with particle sizes of ∼12-14nm. Nanoparticles of undoped and Co-doped samples were synthesized by a polymerized complex method and were characterized using x-ray diffraction and transmission electron microscopy. The magnetic properties of the nanoparticles were determined using vibrating sample magnetometry. The undoped samples exhibit a diamagnetic behavior, whereas all the Co-doped samples are ferromagnetic having the specific magnetizations of ∼0.011-0.038 emu/g at 10 kOe. The finding of room temperature ferromagnetism in the Co-doped samples would allow an enhanced flexibility for applications.
