  The paper by G. R. Berdiyorov, M. V. Milosevic, and F. M. Peeters [Phys. Rev.
B 81, 144511 (2010)] studies theoretically the dynamic properties of a
superconducting loop. The authors claim that their consideration of asymmetric
loop relates to our experimental results in this field. We point out that this
claim is incorrect and explain shortly the true paradoxical essence of the
results of our measurements of asymmetric superconducting loop.
