Figure 6: Illustration of electrical control of magnetism in mixed phase BFO thin films.
From: Electrically controllable spontaneous magnetism in nanoscale mixed phase multiferroics
(a) LCP-PEEM image of a box-in-box electrically switched area, in which the mixed phase stripes are erased in the area indicated by a red box by scanning with a PFM tip at +24 V DC bias and returned by applying −8 V DC bias in the area indicated by a green area. (b) XMCD-PEEM image of same area as in a showing magnetic contrast from the mixed phase structures. The magnetic moments between the red and green boxes are erased by the electric field and the magnetic moments in the green box are turned on again.
