Comments and conditions

Ellipsometry sample: 100 nm thin film of electron beam evaporated EuS deposited on a 0.5 mm thick Si substrate held at room temperature. The base vacuum of the system was ~6×10^-8 Torr whereas during electron-beam evaporation of EuS it was at ~2×10^-6 Torr.

Conditions

film thickness: 100e-9
substrate: Si

About EuS (Europium sulfide)

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.
