Abstract
Dysprosium and Indium doped Co2Z hexaferrite Ba3Co2InyDyxFe23.9-xO41 (where x = 0.0, 0.05, 0.1, 0.15, 0.2 and y = 0.1) were fabricated by sol–gel auto-combustion method. The structural studies were done by XRD and TEM which confirms that prepared samples have a pure Z-type phase. The magnetic studies were done by Vibrating Sample Magnetometer and Mossbauer Spectroscopy. The magnetic hysteresis loop of these samples gives us the value of saturation magnetization, coercive field, and remanence magnetization, from these values we found that Ba3Co2In0.1Dy0.2Fe23.7O41 has the highest saturation magnetization value of 89.065 emu/g. Mossbauer spectra fitted with six sextets of six sites least square fitting gives us information about the presence of Fe3+ state in the sample and that there is no deformation in lattice sites by doping with Dysprosium and Indium dopants as magnetic field vary slightly.
