A growing interest in ferro electromagnetic materials has increased over the years due to the possibilities and advances it will contribute to the industrial and research fields. These materials are applied explicitly to magnetoelectric devices, including those critical to building different types of memory elements. This advancement can be possible due to both ferroelectric and antiferromagnetic ordering existing simultaneously. Bismuth iron titanate (Bi5Ti3FeO15) is represented by these characteristics, making it a ferro electromagnetic material known as multiferroic. Multiferroic substances are of extreme significance since they carry the potential to be used in the electronics industry as well as in electrical engineering. A study by Mazurek et al. expands on the magnetic properties of Bi5Ti3FeO15. Their preparation consists of mechanical activation, a high-energy ball milling process where elemental precursors are repeatedly fragmented, flattened, welded, and fractured. This technique was used in hopes of allowing the preparation of Bi5Ti3FeO15 to reach the industrial scale making the material accessible to more developments. It was then concluded that mechanical activation is a more straightforward method for obtaining the material, yet the milling product still required thermal treatment to complete the reaction. The process to produce Bi5Ti3FeO15 must still be improved and investigated to implement it in future productions.
