Peculiar roles of spins in the thermal conductivity of pure and doped La2CuO4: Comparison with CuGeO3
نویسندگان
چکیده
In-plane and out-of-plane thermal conductivities (κab and κc) are measured on single crystals of pure, 1%-holedoped, and 1%-Zn-doped La2CuO4. The roles of magnons and the spin stripes in the heat transport in these samples are discussed. Comparison with the heat transport in CuGeO3, which shows similar κ(T ) behavior as that of La2CuO4, gives us a lesson of how the heat transport can probe the difference in the spin ground state.

Lu3+/Yb3+ and Lu3+/Er3+ Co-doped Sb2Se3 nanomaterials were synthesized by a Co-reduction method in hydrothermal condition. Powder XRD patterns indicate that the LnxLn′xSb2-2xSe3 Ln: Lu3+/Yb3+ and Lu3+/Er3+ crystals (x= 0.00-0.04) are isostructural with Sb2Se3. The cell parameters were increased for compounds upon increasing the dopant content (x). SEM and TEM images show that Co-doping of Lu3+/...

متن کاملRapid suppression of the spin gap in Zn-doped CuGeO3 and SrCu2O3.
The influence of nonmagnetic impurities on the spectrum and dynamical spin structure factor of a model for CuGeO3 is studied. A simple extension to Zn-doped Sr Cu2 O3 is also discussed. Using exact diagonalization techniques and intuitive arguments we show that Zn doping introduces states in the spin-Peierls gap of CuGeO3. This effect can be understood easily in the large dimerization limit whe...
