Crystal-field study in rare-earth-doped semiconducting YBiPt
نویسندگان
چکیده
Electron spin resonance ~ESR! and magnetic-susceptibility experiments in the rare-earth-doped (R5Nd, Er, and Yb! cubic semiconducting YBiPt allow estimates of the fourth (A4) and sixth (A6) order crystal-field parameters for this compound. It is found that these parameters are of the same order for all the R studied. On the other hand, no crystal-field effects were found for the Gd doped single-crystal system. Consistent with the small gap semiconducting character of the YBiPt intermetallic compound, a Dysonian ESR line shape with no g shift and Korringa broadening was observed. @S0163-1829~99!10925-1#

Efficient electromagnetically induced transparency in a rare-earth doped crystal
We have observed up to 100% transmission of a probe field at line center due to electromagnetically induced transparency (EIT) in an optically dense rare-earth crystal of Pr 3+ doped YzSiOs at 5.5 K. We also have examined both laser field intensity and temperature dependence of the EIT. Efficient EIT in this crystal opens potential applications such as efficient high-resolution image processing...

We report on the synthesis and structural characterization of novel semiconducting heterostructures composed of cadmium selenide (CdSe) quantum dots (QDs) attached onto the surfaces of novel high-surface area, porous rare-earth-ion doped alkaline earth titanate micron-scale spherical motifs, i.e. both Eu-doped and Pr-doped CaTiO3, composed of constituent, component nanoparticles. These unique m...

Effect of Bismuth Doping on the Magnetic Properties of Rare-Earth Orthoferrites by Kelsey A. Collier The purpose of this experiment was to investigate the magnetic properties of bismuth-doped rare-earth orthoferrites, prompted by scientific interest in and the possible device applications of multiferroics. The magnetic susceptibility of single-crystal samples of pure and bismuth-doped orthoferr...
متن کاملInterfacing superconducting qubits and telecom photons via a rare-earth-doped crystal.
We propose a scheme to couple short single photon pulses to superconducting qubits. An optical photon is first absorbed into an inhomogeneously broadened rare-earth doped crystal using controlled reversible inhomogeneous broadening. The optical excitation is then mapped into a spin state using a series of π pulses and subsequently transferred to a superconducting qubit via a microwave cavity. T...
