The magneto-optical characteristics of the europium fluoride crystal were measured. They are 100% -55% higher than the corresponding values for the popular TGG crystal. Taking into account better spectral characteristics in the mid-IR range and good thermo-optical characteristics, it can be concluded that the use of europium containing fluorides is promising in the development of Faraday isolators for mid-IR lasers.

Europium-containing fluorides show promising magneto-optical properties, making them promising for mid-IR laser Faraday isolators.
