متن کاملRenormalization of the elementary excitations in hole- and electron-doped cuprates due to spin fluctuations
Extending our previous studies we present results for the doping, momentum, frequency, and temperature dependence of the kinklike change of the quasiparticle velocity resulting from the coupling to spin fluctuations. In the nodal direction a kink is found in both the normal and superconducting state while in the antinodal direction a kink occurs only below Tc due to the opening of the supercond...
متن کامل1 Superconductivity and spin fluctuations in the electron - doped infinitely - layered high
We report Cu NMR studies on uniaxially aligned and unaligned powder samples of an electron-doped infinitely-layered high Tc cuprate superconductor Sr0.9La0.1CuO2 (Tc =42 K). We measured the nuclear spin-lattice relaxation rate 1/T1 up to 800 K. We found from the temperature dependence of 1/T1T that the wave-vector-averaged spin susceptibility is highly enhanced by spin-fluctuations in the norma...
متن کاملElectronic theory for the normal-state spin dynamics in Sr2RuO4: Anisotropy due to spin-orbit coupling
Using a three-band Hubbard Hamiltonian we calculate within the random-phase approximation the spin susceptibility, x(q,v), and nuclear magnetic resonance spin-lattice relaxation rate, 1/T1, in the normal state of the triplet superconductor Sr2RuO4 and obtain quantitative agreement with experimental data. Most importantly, we find that due to spin-orbit coupling the out-of-plane component of the...
متن کاملinvestigation of the electronic properties of carbon and iii-v nanotubes
boron nitride semiconducting zigzag swcnt, $b_{cb}$$n_{cn}$$c_{1-cb-cn}$, as a potential candidate for making nanoelectronic devices was examined. in contrast to the previous dft calculations, wherein just one boron and nitrogen doping configuration have been considered, here for the average over all possible configurations, density of states (dos) was calculated in terms of boron and nitrogen ...
