Electric Field Gradient Studies of Actinide Compounds

This work explores materials made from very heavy elements such as uranium, neptunium, and plutonium. These elements behave differently from normal metals because their electrons are more complex, which leads to unusual magnetic behavior. Using advanced computer-based physics methods, the study examines how the atoms in these materials are arranged and how they interact magnetically.It also investigates extremely small electric and magnetic signals inside these materials, which reveal how electrons move and how atoms influence each other. Several combinations of heavy and lighter elements, such as gallium, aluminum, indium, and lead, were analyzed, and the computer results match well with experiments.This work clearly explains where these tiny internal signals come from. It shows that the heavy atoms mainly contribute through their special f electrons, while the lighter atoms contribute through their p electrons. This understanding can help scientists design better materials for future technologies.
