text: FIG. 2. (color online) XMCD asymmetry versus applied ﬁeld 
  along the [110] axis at 2 K, for a Fe (2 nm)/(Ga,Mn)As 
  (a) Fe L3, total electron yield; (b) Mn L3, 
  (10 nm) ﬁlm. 
  total electron yield; (c) Mn L3, ﬂuorescent yield. Black and 
  red points are data for increasing and decreasing ﬁelds respec- 
  tively; lines are to guide the eye.
