Successful combination of ferromagnetism and photoluminescence properties in lead-free ferroelectric Bi0.5Na0.5TiO3 materials

Lead-free ferroelectric Bi0.5Na0.5TiO3 materials integrated ferromagnetism and photoluminescence at room temperature. Fe and Sm cations were used as the magnetic and photoluminescence sources for the co-modified host Bi0.5Na0.5TiO3 materials. The (Fe, Sm)-modified Bi0.5Na0.5TiO3 materials were fabricated by using the sol-gel method. The structure of the samples was studied through X-ray diffraction and Raman scattering, which indicated that a single perovskite structure was successful fabricated.

Application of directional derivative method to determine boundary of magnetic sources by total magnetic anomalies

This paper presents the Directional Derivative method to determine location and boundaries of the magnetic directional structure sources through a new function DG (Directional Gradient - DG). Algorithm and computer program are made a code by Matlab language to attempt to calculate on 3D models in the compare with Horizontal derivative method (HG).
