text: FIG. 1. 
  (color) Main ﬁgure: Major (red/black) and minor 
  (green) hysteresis loops along the [110] axis at 5 K, for a 
  Fe (2 nm)/(Ga,Mn)As (20 nm) ﬁlm, and the hysteresis loop 
  for a control (Ga,Mn)As (20 nm) ﬁlm along the same axis 
  (blue). Left inset: Magnetization versus temperature for the 
  Fe/(Ga,Mn)As ﬁlm at remanence (black) and under a 500 Oe 
  applied ﬁeld (red). Right inset: Exchange bias ﬁeld versus 
  thickness d of the (Ga,Mn)As ﬁlm (points) and ﬁt showing 
  1/d dependence (dashed line).
