| Popis: | Due to their large effective magnetic moment, Dy3+-doped materials have attracted much interest for magneto-optical applications. In this paper, we report highly Dy3+ doped multicomponent glasses with concentrations from 40 wt.% to 75 wt.% and their magneto-optical properties. A Verdet constant of −7.4 rad/T/m at 1950 nm was measured with the 75 wt.% Dy3+-doped glass. This is the highest reported Verdet constant around 2 µm for a paramagnetic glass. Our experimental results show that highly Dy3+-doped glasses are promising isotropic magneto-optical materials for applications in the 2 µm wavelength region. |
