“…This structure indicates that the samples can easily exhibit absorption and condensation of water vapor as Ge 4+ ions increase. According to Hemeda [22,23] and Ecklet [24] the increase of Cu 2+ ions leads to the increase of porosity. Also Visser et al [25] state that the non magnetic particles and trace amount of impurities forming a non magnetic grain boundary leads to the reduction of grain size and increasing of porosity.…”

Cu-Ge ferrite was prepared using the standard ceramic method. The creep rate of polycrystalline Cu1+xGexFe2-2xO4 ferrite has been measured as a function of time at room temperature. It is found that the indentation length increases with the increase of both time and applied load. A regime of individual creep curves is observed for the first and second stages. It is not possible to record the third stage of the curve as usually happened in an ordinary creep test, because fracture of the samples does not occur. The slope is found to increase with increasing germanium and copper content in the steady state region. The high value of n (stress exponent factor) indicates that the dislocation creep is the dominate mechanism. The porosity arrangements developed within the specimens were examined using optical microscope. The results are discussed with regard to models describing the role of the steady state creep rate of metals. The morphology of the samples shows that the porosity is increased by increasing both copper and germanium ions

“…To obtain ferrite materials, a ceramic method was used due to its simplicity and high quality single phase perovskites that can be obtained. [18][19][20] BaCO 3 and Fe 2 O 3 were mixed and grounded in an agate mortar for 10 hrs to ensure homogeneity. The mixtures were pre-sintered at 900 o C for 12 hrs and gradually cooled to room temperature.…”

Remarkable magnetic enhancement of type-M hexaferrite of barium in polystyrene polymer

We demonstrate that the promising effect of inclusion of single magnetic-domain type-M hexaferrite of barium (BaM) particles in polystyrene (PS) polymer (BaM/PS weight ratio = 2/1). The results show that the coercivity of BaM particles remarkably increases from 714 to 3772 Oe and remanence increases from 2.07 to 5.41 emu.g−1 when they embedded into PS. Moreover, magnetic coercivity and squareness of the BaM-PS are significantly larger, and is comparable with corresponding values of other BaM-polymer composites. Therefore, BaM-PS composite enforce itself as the modern potential materials with tendency of replacing existing composite materials in several applications.

Hexaferrite Sr 1−x La x Fe 12−x (Cu 0.5 Co 0.5) x O 19 (0 ≤ x ≤ 0.50) magnetic powders and magnets were synthesized by the solid-state reaction method. The phase compositions of magnetic powders were investigated by X-ray diffraction. The single magnetoplumbite phase is obtained in magnetic powders with x from 0 to 0.40. At x = 0.50, CoFe 2 O 4 ,a n dα-Fe 2 O 3 were observed. The morphology of the materials was characterized by a field-emission scanning electron microscopy. The particles were hexagonal platelets. Magnetic properties of the materials were measured by a permanent magnetic measure equipment. The remanence of the materials increases with x from 0 to 0.50. However, the intrinsic coercivity and magnetic induction coercivity of the materials increase with x from 0 to 0.15, and decreases when x varies from 0.15 to 0.50. Accordingly, the maximum energy product of the materials first increases with x from 0 to 0.35, and then decreases when x exceeds 0.35.
