Studying Dielectric and Magnetic Properties of Nano Ferrite Functionally Graded Materials

Abstract Functionally graded materials (FGMs), with ceramic –ceramic constituents are fabricated using powder technology techniques. In this work three different sets of FGMs sample were designed in to 3 layers, 5 layers and 7 layers. The ceramic constituents were represented by hard ferrite (Barium ferrite) and soft ferrite (lithium ferrite). All samples sintered at constant temperature at 1100oC for 2 hr. The magnetic properties showed an increase in coercive force (Hc) with increased number of layers. The dielectric properties measured at room temperature with constant frequency 1 MHZ. The results showed the dielectric constant increase with the increase the number of layers from (1.39×10-2) to (2.83×10-2).
