Peculiar roles of spins in the thermal conductivity of pure and doped La_{2}CuO_{4}: Comparison with CuGeO_{3}

Yoichi Ando, X. F. Sun, J. Takeya +1

In-plane and out-of-plane thermal conductivities (κ_{ab} and κ_{c}) are measured on single crystals of pure, 1%-hole-doped, and 1%-Zn-doped La_{2}CuO_{4}. The roles of magnons and…
