• Magnetic field effects on the structural phase transition in p-Pb_<1-x>Ge_xTe(x=0.01)and n-Pb_<1-x>Ge_xTe(x=0.008) have been investigated by infrared magneto-transmission measurements in the megagauss range using the single-turn coil technique. We have found that the transition temperature T_C increases by 14 K by the application of magnetic fields of 90 T parallel to the [111] direction in p-type samples whose T_c at 0T is 34 K. Similar dependence has been observed in n-type samples. These results not only provide a support to the previous work by Takaoka and Murase in the low field range below 7 T but also show that the magnetic field effect on the phase transition is even enhanced in the ultra-high magnetic field range without any saturation. We have estimated the critical field of the possible structural phase transition induced by magnetic fields in PbTe.
