Abstract
This paper describes the effect of the substitution of Nd3+ ions in Barium-Strontium Hexaferrite (Ba0.6Sr0.4)1-xNdxFe12O19 with x = 0.01, 0.03 and 0.05, on the energy of the product. All samples were made from raw materials of barium (II) carbonate, strontium (II) carbonate, neodymium (III) oxide, and iron (III) oxide which each have a purity of > 99% which was processed by the solid-state reaction method using high energy milling with a rotating speed of 750 rpm.The crystal structure and phase formed are characterized using an X-ray diffractometer. Scanning electron microscopy is used for surface morphology analysis and permagraph is used for hysteresis characterization so that the product energy can be calculated. X-ray diffraction analysis showed that all phase samples have an orthorhombic structure and space group P nma. Surface morphology is almost homogeneous with heterogeneous shapes and the average particle size ranges from 200-800 nm. The maximum product energy obtained is 165.4kGOe in the sample x = 0.05.
