Measurement of de Haas-van Alphen Effect with Hybrid Magnet(Transport and Fermiology)
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_<7-δ> and Tl_2Ba_2CuO_<6+δ> 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.
