The Effect of Heating the Composite Material BSF and BST Varying Temperatures for Magnetic Properties Created by the Method of Mechanical Alloying

EasyChair Preprint 461

Abstract

In this research carried out investigations on the magnetic properties of the composite BSF-BST (ferromagnetic and ferroelectric) prepared by the method of milling and sonication. The result of the basic material milling BSF and BST process and obtained particle size for the material was nearly 20- 4 µm . Analyzed by X-Ray Crystal size of 27 nm was found in B7S3T, to B7S3F in which mean crystallite size of only 18 nm. Morphology of composite particles can be seen from the results of SEM. Heating at 1000 and 1100oC temperature for 2 hours and its the magnetic properties changes of the material BSHF is indicated to changes in the intrinsic coercivity of 320.4 kA / m to 126 kA / m and the rising value of remanence Mr, also an increase in the saturation value Ms from 0.1263 to 0.1662 T. And we hope this materials can be promoted as multiferroic material.
