Cr-doping induced ferromagnetic behavior in antiferromagnetic EuTiO3 nanoparticles

► High quality EuTi1−xCrxO3 (x = 0.0, 0.02, and 0.04) nanoparticles with size about 100 nm were synthesized by simple sol-gel technique. ► Structural and magnetic properties of these nanoparticles were investigated. ► G-type antiferromagnetic (G-AFM) order of EuTiO3 can be significantly modified with slight Cr-doping. ► Ferromagnetism (FM) is greatly enhanced for EuTi1−xCrxO3 (x = 0.02 and 0.04).
