Abstract: An apparatus to measure the de Haas-van Alphen effect in steady high magnetic field has been constructed by using hybrid magnets at Tohoku University. Fermi surfaces were investigated on cuprate high-temperature superconductor and rare earth antimonide. The spectral analyses were performed by using the maximum entropy method as well as the Fourier transformation. In magnetically oriented YBa_2Cu_3O_ and Tl_2Ba_2CuO_ powder , the spectral density shows a peak at 456 T and 400 T, respectively. A slight change of extremal cross-section was found in PrSb above 15 T.
