Faraday Rotation Effect of Highly Tb₂O₃/Dy₂O₃-Concentrated B₂O₃−Ga₂O₃−SiO₂−P₂O₅ Glasses

Preparation and magnetic properties of TbF3 containing oxide fluoride glasses

“…Therefore it is obvious that the magnetic moment is derived only from a trivalent terbium ion. The atomic content of Tb 3+ in 40TbF 3 -20BaF 2 -10AlF 3 -30GeO 2 was calculated as 11%, which is comparable to that reported for oxide glasses as the maximum one, 12% [11]. In addition, the saturation behavior might result from the Tb 3+ (#)-O 2À -Tb 3+ (") superexchange interaction, which prevented orientation of Tb 3+ magnetic moments to the applied magnetic fields in the case of the oxide glasses [12].…”

Complex Faraday Rotation in Microstructured Magneto‐optical Fiber Waveguides

“…As already mentioned, the Verdet constant resulting from doping with multiple rare-earth ions is not always a simple linear sum of the contributions of each ion, raising the possibility of very high values of V B . [ 44 ] As a dopant species, Tb 3 + offers the highest paramagnetic susceptibility ( J = 6 and g = 1.46). [ 45 ] Hence, all commercially available MO glasses rely on massive Tb 3 + -doping.…”
