Faraday effect in CdMnTe nanocrystals grown by the laser deposition method

Temperature Dependence of Faraday Rotation of Glass Optical Fibers Doped with Quantum Dots of CdSe and CdMnTe

“…But, in the case of the CdMnTe doped fiber, exciton splitting due to sp‐d exchange interactions with the Mn 2+ ions was also contributed . In addition, the size of nanoparticles and the interatomic lattice spacing also affect exciton confinement such as the exchange interaction of electrons and holes, which mixes different electron and hole spin states, causing modifications in the magnetic sensitivity . It is known that the semiconductor nanocrystals such as CdSe or CdMnTe QDs have already been found to have a significant effect on the magnitude of the Faraday rotation in bulk glasses .…”

[18,22,49] It is known that the semiconductor nanocrystals such as CdSe or CdMnTe QDs have already been found to have a significant effect on the magnitude of the Faraday rotation in bulk glasses. [3,10,18,46,[48][49][50] However, it should be noted that since the concentration of CdSe and CdMnTe QDs in the fibers is quite different, direct comparison of the FRA of the two fibers is not appropriate.…”

Magneto-optic studies of rare earth containing sodium silicate glasses and semiconductor quantum dots in glass composites: Nonlinear effects

“…Nikitin et Al. [15] prepared Cd 1 − x Mn x Te Nanocrystals embedded in an SiO 2 matrix and a study of the Faraday effect in this semi-magnetic semiconductor nano-crystal has revealed large enhancements of this effect, with respect to the bulk crystal. Faraday effect enhancement manifesting itself in strong nonlinear Faraday rotation, has been observed [16,17].…”

Magnetooptic properties of semiconductor quantum dots in glass composites

“…This exchange interaction constitutes an interplay between the semiconductor and magnetism giving a large Faraday rotation in three dimensionally confined clusters [15]. Nikitin et al [19] prepared Cd 1Àx Mn x Te nanocrystals embedded in an Sio 2 matrix. A study of the Faraday effect in these semimagnetic semiconductor nanocrystals has revealed large enhancements of the effect, when compared to the bulk Cd 1Àx Mn x Te crystal.…”
