在超导临界场{ital B}{sub {ital c}2}为17.95 T时，沿（100）方向和1.5 K时，在V{sub {ital c}2}上和{ital < 3}Si中观察到磁化中的量子振荡，在逆场（de Haas—van Alphen效应）中周期性。振荡在两个场域中具有相同的频率（{正负}0.3%）。通过对振幅的比较表明，量子振荡测量可以用来确定超导相中的场密度分布。
Quantum oscillations in the magnetization, periodic in inverse field (de Haas--van Alphen effect), have been observed in V{sub 3}Si both above as well as {ital below} the superconducting critical field {ital B}{sub {ital c}2} of 17.95 T for fields along the (100) direction and at 1.5 K. The oscillations have the same frequency ({plus minus}0.3%) in the two field regimes. It is shown by intercomparing the amplitudes that quantum oscillation measurements can be used to determine the field density distribution in the superconducting phase.
