Magnetic properties of nanocrystalline Mn{sub 1-x}Zn{sub x}Fe{sub 2}O{sub 4}
Abstract
Nanocrystalline Mn{sub 1-x}Zn{sub x}Fe{sub 2}O{sub 4} (x = 0, 0.1, 0.3, 0.5, 0.7, 0.9, 1.0) were prepared via solution combustion method. Structural and morphology of Mn-Zn ferrites were characterized by X-ray diffraction (XRD) and Transmission Electron Microscopy (TEM). Magnetic properties were carried out using vibrating sample magnetometer (VSM) at room temperature (RT) up to maximum field of 1.5 T. The room temperature real and imaginary part of permeability (μ′ and μ″) has been measured in the frequency range of 1MHz to 1GHz. The room temperature XRD patterns exhibits the spinel cubic (Fm-3m) structure and broad XRD patterns shows the presence of nanoparticles. The imaginary part of the permeability (μ″) gradually increased with the frequency and took a broad maximum at a certain frequency, where the real permeability (μ′) rapidly decreases, which is known as natural resonance. The coercive filed values are low, hence probability of domain rotation is also lower and the magnetization decreased with zinc substitution. The values of μ′ and μ″ increases sharply, attained a maximum and then decreases with zinc content.
