INFO
Europium sulfide, EuS
Europium sulfide (EuS) is a compound characterized by its ferromagnetic behavior at low temperatures, with a Curie temperature of approximately 16.6 K. In the realm of optical applications, EuS has been studied for its potential in magneto-optical devices and as a component in spintronic systems. Its strong interaction with light and magnetic fields offers the possibility of modulating optical signals via magnetic controls. Additionally, thin films of EuS can be applied to other materials to enhance their magneto-optical properties. Though not as commonly used as europium-doped glasses or crystals, Europium sulfide offers a unique set of magnetic and optical properties that are of interest for specialized applications in both research and technology.Other name
