    Sol-Gel Synthesized Cerium (Ce) Substituted M type Hexaferrites: Evaluation of Electrical and Magnetic Properties
    (Library Information Services, COMSATS University Islamabad, Lahore Campus, 2020) MUSTANSAR JAVID; CIIT/SP19-RPH-037/LHR; Dr. Mukhtar Ahmad; LHR TP 6374
    Cerium (Ce) substituted M-type hexaferrites BaCexFe12-xO19 (x= 0.0, 0.05, 0.10) synthesized by the use of sol-gel technique. After synthesis, X-ray diffractometer (XRD) was used to confirm crystal structure of M-type hexagonal ferrites. The evaluation of grain size and analysis of external morphology of synthesized hexaferrites was being done by scanning electron microscope (SEM). To analyze the Infrared absorption, Fourier transform infrared spectroscope (FTIR) has been used. The DC electrical resistivity has been studied by the use of two point probe technique. The increase in DC resistivity with increasing Ce-contents as the Fe+3 ions responsible for conduction have been reduced. Magnetic characteristics as saturation magnetization (Ms), remenance (Mr) and coercive force (Hc) are being calculated with a vibration sample magnetometer (VSM).
