Title: De Hass-van Alphen effect in YBCO

Measurement of the de Haas-van Alphen effect in YBa{sub 2}Cu{sub 3}O{sub 6.97} in pulsed, magnetic fields peaking at 100 T in powdered material with the field applied along the c-axis reveal two pieces of the Fermi surface. Their cross sections are 0.56 kT (0.054 {angstrom}{sup {minus}2}) and 0.78 kT (0.075 {angstrom}{sup {minus}2}) with effective masses of 2.8 and 4.4 respectively.
