Investigation of Mixed Electronic States in Dy3Fe5O12 Produced by Doping with Nickel
Rare earth iron garnets are scientifically significant because the versatility of cation substitution in various geometrical locations results in adjustable and varied characteristics for magnetic devices and optoelectronics applications. In a rare earth iron garnet, such as Dy 3 Fe 5 O 12 , electro...

compounds through X-ray photoelectron spectroscopy. Scanning electron micrographs demonstrated that nanoparticles with whiskers in morphology with the existence in soft agglomeration. The impact of nickel replacing the cubic formation of garnets was explored using X-ray diffraction and Fourier transform infrared spectroscopy. In addition, the Fe: Ni ratio affects the magnetization and anisotropy of Dy
