説明
Dynamical Faraday rotation measurement with the high magnetic fields of-16 T has revealed the presence of microscopic magnetic coupling among trivalent terbium (Tb3+) ions at low temperature in Tb2O3-riched borate glasses, caused by the superexchange interaction via oxygen ion. Doping by the divalent manganese (Mn2+) ions into Tb2O3-B2O3 glass made the magnetic correlation temperature (TMC) rising from 120 to 250 K, due to the formation of stronger antiferromagnetic couplings between Tb3+ and Mn2+ ions. The repetitional application of the 16T-pulsed magnetic fields at lower temperature than 30 K destroyed the magnetic couplings so that the Faraday rotation could be enhanced. After the operations, the Faraday rotation curves at 300 K were drastically changed upon the incorporation of Mn2+ ions.
