Spin-lattice relaxation of Fe3+ in ZnS ; experimental evidence for optical phonons
نویسندگان
چکیده
2014 The spin-lattice relaxation of the Fe3+ ion in cubic ZnS has been studied between 1.3 and 300 K by pulse saturation, progressive saturation and broadening of the E.P.R. line. In ZnS, the Fe3+ ion is more strongly coupled to the lattice than the isoelectronic ion Mn2+. For T > 50 K, the optical phonons contribute to the relaxation, and are responsible for a strong line broadening at 300 K. LE JOURNAL DE PHYSIQUE TOME 40, DÉCEMBRE 1979, .

Strong spin-phonon coupling between a single-molecule magnet and a carbon nanotube nanoelectromechanical system.
Magnetic relaxation processes were first discussed for a crystal of paramagnetic transition ions. It was suggested that mechanical vibrations of the crystal lattice (phonons) modulate the crystal electric field of the magnetic ion, thus inducing a 'direct' relaxation between two different spin states. Direct relaxation has also been predicted for single-molecule magnets with a large spin and a ...
متن کاملSpin dynamics and electronic states of N-V centers in diamond by EPR and four-wave-mixing spectroscopy.
We applied a new phase-modulation technique for nonlinear laser spectroscopy with sub-Hz relative resolving power to measure fundamental relaxation processes of the N-V center in diamond. Complementary EPR experiments versus temperature establish the ground-state spin character in the absence of optical illumination and show that spin-lattice decay occurs via two-phonon processes involving the ...
متن کاملSpin-lattice relaxation in amorphous silicon. Evidence of anomalous temperature dependences
2014 We have investigated the spin-lattice relaxation of localized states in evaporated amorphous silicon films. Temperature and concentration dependences of the relaxation rate have been measured in the temperature range 4.2-290 K. Below 10 K a phonon bottleneck is present. Between 10 and 100 K, a single phonon process predominates. It can be accounted for assuming a significant exchange inter...
متن کاملSpin-flip limited exciton dephasing in CdSe/ZnS colloidal quantum dots.
The dephasing time of the lowest bright exciton in CdSe/ZnS wurtzite quantum dots is measured from 5 to 170 K and compared with density dynamics within the exciton fine structure using a sensitive three-beam four-wave-mixing technique unaffected by spectral diffusion. Pure dephasing via acoustic phonons dominates the initial dynamics, followed by an exponential zero-phonon line dephasing of 109...

Spin-related emission properties have important applications in the future information technology; however, they involve microscopic ferromagnetic coupling, antiferromagnetic or ferrimagnetic coupling between transition metal ions and excitons, or d state coupling with phonons is not well understood in these diluted magnetic semiconductors (DMS). Fe3+ doped ZnSe nanoribbons, as a DMS example, h...
