Description
The temperature and magnetic field dependences of the thermal conductivity κ(T, B) have been investigated for La0.52Ca0.48MnO3. κ(T, B) markedly changes at the phase transition between the charge-orderd antiferromagnetic (CO-AFM) state and the ferromagnetic (FM) metal state. κ(T, B) is enhanced in the FM state because the phonon scattering by the local Jahn-Teller strain around Mn3+ spins is released in the metallic phase. The κ(T, B) behaviors can be understood on the basis of the volume fraction ratio of the FM and CO-AFM phases
