On the possibility of the Aharonov-Bohm effect observation in transport measurements in charge-density-wave conductor
We have studied the conditions for the observation of the Aharonov-Bohm oscillatory magnetic flux-dependent component in the transport charge-density-wave (CDW) current in a thin film with columnar defects placed in a strong magnetic field. The flux through an isolated defect exceeds the magnetic fl...

The flux through an isolated defect exceeds the magnetic flux quantum Ф₀, the defect serves as a solenoid. We predict the percolation and instanton contributions to the oscillatory CDW current. It has been shown that even at moderate temperatures at high enough concentration of columnar defects the amplitude of the ABE produced oscillatory current may reach of order of 10⁻⁴ of the transport current. The period of the oscillations over the magnetic flux is Ф₀/2.
