Current instability in bismuth single crystals in a transverse magnetic field
Zhilyaev I. N.
When a current is passed through a high-quality bismuth crystal in a transverse magnetic field at liquid-helium temperature, monochromatic electromagnetic oscillations arise. The oscillation frequencies measured for samples of various thicknesses agree with the instability model proposed by Azbel\ Perturbations excited near an end of the sample are amplified.
