Abstract (300 words maximum)
There are many different combinations of elements that will make different materials with different electrical and magnetic properties. Most of these materials’ electric and magnetic properties have not been studied, so the correlation between the compounds that makeup the materials and the electric and magnetic properties of them are not fully understood yet. Research must continue in order to collect data on different materials. This will give us a better understanding of the properties associated with each material, compound, and element. The electric and magnetic properties of most materials are not understood. The purpose of this research is to gain insight into the electric and magnetic properties of certain materials. The flux method was mainly used to form the single crystalline materials. The flux method is a crystal growth method that uses a flux to dissolve materials. Crucibles were filled with elements to be formed into the desired single crystalline material. The crucibles were then flame sealed in a glass tube under vacuum. The crucibles were then placed in a muffle furnace. With gallium as the flux, the elements dissolved and then formed single crystals of the desired material. Immediately after the crucibles were taken out of the furnace, a centrifuge was used to separate the molten gallium from the single crystalline material. The Bridgman method was also used to make some single crystalline materials and arc melting synthesis was used to make polycrystalline materials. The electric and magnetic properties of the crystalline materials were then measured using a SQUID magnetometer. The electric and magnetic properties of these materials are now understood.
