Magnetothermal transport in monoclinic Nd$_{2}$Ti$_{2}$O$_{7}$

ORAL

Abstract

The monoclinic Nd$_{2}$Ti$_{2}$O$_{7}$ is an interesting material due to the existence of a novel field-induced slow spin relaxation (SSR) in the paramagnetic state. The SSR is attributed to the cooperative relaxation mode formed through the spin-spin interactions between partially polarized spins. Here we report the magnetothermal transport measurement on Nd$_{2}$Ti$_{2}$O$_{7}$ single crystals. The zero field thermal conductivity is dominated by the phonon contribution. The magnetothermal conductivity reveals significant field dependence. The field and temperature dependence is discussed in connection with the field-induced slow spin relaxation. .
