چکیده انگلیسی
M-type hexaferrites with Co2+ and Ni2+ions substituting for Fe3+ ions (Ca0.30Sr0.35La0.35Fe12.0âx(Co0.5Ni0.5)xO19, 0.0â¯â¤â¯xâ¯â¤â¯1.0) were prepared by the traditional solid state method. X-ray diffractometer (XRD), field emission scanning electron microscopy (FE-SEM), physical property measurement system-vibrating sample magnetometer (PPMS-VSM) have been employed to study the microstructures and magnetic properties of hexaferrites. XRD patterns showed that the single magnetoplumbite phase is obtained if Co-Ni content (x)â¯â¤â¯0.4 and impurity phases are observed in the structure when Co-Ni content (x)â¯â¥â¯0.4. FE-SEM micrographs showed that the hexaferrites with hexagonal platelet-like grains is obtained. The saturation magnetization (Ms), remanent magnetization (Mr), Mr/Ms ratio, magneton number (nB), coercivity (Hc), magnetic anisotropy field (Ha) and first anisotropy constant (K1) decrease with increasing Co-Ni content (x) from 0.0 to 1.0. And our reported results with tunable Hc and Mr can be used for recording applications.
