Abstract

Ca0.75(La,Al)0.25Fe12O19 hexaferrite ferrite are analysis using  are synthesise and characterised  using  X-ray diffraction (XRD) was used to analyse the phases of the ferrite magnets. An SEM study is carried out  with an Energy Dispersive X-Ray Spectroscopy (EDXS) was used to analyse the microstructure development of the hexaferrite samples (EDS). The grain shape changed as the temperature of sintering increased. This ferrimagnetic hysteresis curve was acquired by using a Vibrating Sample Magnetometer in a room with room temperature (VSM). After sintering at 850 oC and 950oC, the crystallite parameters (a,c) were also computed.  The magnetic responces are recoded Ms = 49.62 emu/g ,Mr = 53.97 emu/g, respectively, while Mr were 28.66 emu/g and 32.77 emu/g, respectively, for the saturation and remanent magnetizations. the increase in coercivity is noted with the sintering temperature, Hc, fell from 3.15 kOe to 2.66 kOe. There were significant differences in squareness ratios (Mr/Ms) of samples after sintering at 850oC and 950oC is recorded.
