Fig. 9From: Structural and Magnetic Properties of Transition-Metal-Doped Zn 1−x Fe x O a–c Magnetization vs. field isotherms from 20 to 300 K for x= 0.02, 0.04, and 0.08, respectively. The insets illustrate the isothermal magnetization plots at 2 and 300 K up to +7 and −7 T suggesting the ferromagnetic signature at our investigated systemsBack to article page
