Description
Thermal conductivity κ(T), Seebeck coefficient S(T), and magnetization M(T) have been measured on LaCo0.98M0.02O3 doped with various valence cations M. A sharp and strong κ(T) peak of pristine LaCoO3 around 30K is suppressed for 2+ dopants. Jahn-Teller active Co4+(IS).6Co3+(HS) clusters introduced concomitantly with the hole doping may act as the powerful phonon scattering centers at low temperatures
