Ultrasonic cavitation assisted solvothermal synthesis of superparamagnetic zinc ferrite nanoparticles

Nanoparticles of cubic zinc ferrites (Fd3̄m, a = 8.41(3)-8.44(1) Å) were synthesized as a single phase by an ultrasonic cavitation-assisted solvothermal technique using ethyl alcohol-water mixed solvents at temperatures of 150 C or higher for 18 h or more. The influences of the ultrasonic cavitation...
