Abstract
The de Haas-van Alphen effect has been measured in magnetically oriented powder YBa2Cu3O7 in steady high magnetic fields up to 27 T at the temperature range between 1.8 and 4.2 K. The magnetic fields were generated by hybrid magnets, and the oscillatory magnetization was detected by a modulation method. A broad band centered at 540 ± 30 T, which corresponds to an extremal cross-section of 0.052 ±0.003 A.2, appeared in the Fourier spectrum for H//c-axis. The effective mass was estimated to be 2.1 ±0.5 me.
