✦ Synopsis

Simultaneous measurements of Hall effect and magneto resistance in high pulsed fields up to B ¼ 55 T are presented throughout the full temperature range on the high temperature superconductor La 2À1=8 Sr 1=8 CuO 4 with T c ¼ 17 K: A direct comparison is made between the longitudinal resistivity ðr xx Þ and the Hall coefficient ðR H Þ: Both r 50 T xx ðTÞ and R 50 T H show a distinct extremum around T ¼ 80 K; with lowering temperatures, the field-induced normal state magneto-resistance diverges, the Hall angle increases and R 50 T H decreases up to a saturated value of 1:7 Â 10 À9 m 3 =C: There is no obvious discontinuity in R 50 T H observed when crossing the superconducting/ normal phase transition.
