  It is shown that the Berezinski-Kosterlitz-Thouless phase transition that has
been found in D3-D5 brane systems with nonzero magnetic field and charge
density can also be found by tuning an extra-dimensional magnetic flux. We find
numerical solutions for the probe D5-brane embedding and discuss properties of
the solutions. We also demonstrate that the nontrivial embeddings include those
which can be regarded as spontaneously breaking chiral symmetry.
