Query: Critical magnetic field in holographic superconductor in Gauss-Bonnet
  gravity with Born-Infeld electrodynamics   In the paper using matching method in the probe limit, we investigate some
properties of holographic superconductor in Gauss-Bonnet gravity with
Born-Infeld electrodynamics . We discuss the effects of the Gauss-Bonnet
coupling $\a$ and Born-Infeld parameter $b$ on the critical temperature and
condensate. We find that both of $\a$ and $b$ make the critical temperature
decrease, which implies the condensate harder to form.
  Moreover we study the magnetic effect on holographic superconductor and
obtain that the ratio between the critical magnetic field and the square of the
critical temperature increases from zero as the temperature is lowered below
the critical value $T_c$, which agrees well with the former results. We also
find the critical magnetic field is indeed affected by Gauss-Bonnet coupling,
but not by Born-Infeld parameter.
