The magnetothermal conductivity of high-temperature superconductors (HTS) reflects the scattering processes between the charge carriers, phonons, and vortices. Therefore, the magnetothermal conductivity can provide information about the vortex dynamics. Here, we report thermal conductivity measurements of bulk Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{ital {sub x}} superconductors in an applied magnetic field up to 20 Tesla. The measurements were taken over a wide range of temperatures around {ital T{sub c}}. The superconducting parameters were successfully recovered from the obtained data using the theoretical model developed by Ausloos and Houssa [J. Phys. Condens. Matter {bold 7}, 193 (1995)], in which the change in thermal conductivity in the applied magnetic field is predominantly due to the scattering between the vortex lines in the superconductor and the normal electrons in the Cu{endash}O planes. {copyright} {ital 1997 American Institute of Physics.}
