Europium in Magnetic Materials
Europium is widely used in the creation of magnetic materials, particularly rare earth magnets. These magnets are composed of alloys that combine europium with other elements such as cobalt and samarium. Due to the magnetic properties of europium, these alloys result in incredibly powerful magnets that are used in various applications.
The magnetic properties of europium arise from the behavior of its electrons. Europium contains 65 electrons, with one unpaired electron in its outermost energy level. This unpaired electron creates a magnetic moment, allowing europium to exhibit strong magnetization and magnetic anisotropy.
Magnetic systems that contain europium can be easily manipulated using an external magnetic field, making them useful in a range of applications. Europium-containing magnets are commonly used in hard disk drives, headphones, and electric motors.

Europium in Nuclear Reactors
Europium plays a crucial role in the field of nuclear reactors. The stable isotope europium-155 is used for its high neutron capture cross-section, which makes it useful in controlling nuclear reactions. When europium-155 absorbs a neutron, it produces europium-156, which decays into gadolinium-156. Gadolinium-156 acts as a neutron poison, slowing down the fission process and preventing the reactor from becoming too hot. This is vital for the safe and efficient operation of nuclear reactors.
In addition to its use in controlling nuclear reactions, europium is also used in fuel cells and as a radiation shield due to its strong gamma ray absorption properties. However, it is important to handle europium with care, as it is radioactive and can be harmful if not properly secured.
