Oscillatory phenomena of the type of “flux quantization” have been studied in normal microcylinders in a tilted magnetic field. It is shown that the oscillation period in the flux Φ = HπR2 (H is the magnetic field and R is the cylinder radius) increases with increasing field tilt angle θ relative to the cylinder axis according to a law ΔΦ = Φ0/cosΘ where Φ0 = hc/e is the flux quantum for a normal metal. The experimental data found in the present work agree with such a dependence, which allows us to interpret it as a manifestation of the Aharonov–Bohm effect in solids.
