Figure 6
(a) Schematic illustration of an ME read-head sensor based on a bilayer CFO/BTO heterostructure. (Inset) A transmission electron microscopy image of the CFO/BTO heterostructure grown on a single-crystal STO substrate. (b) Voltage output waveforms (upper) for thin bilayer CFO/BTO films induced by different functions of δH at 1 kHz simulating the expected output voltage signals from a section of a magnetic recording track when using the ME read head. The bits bk written with Iw apply the required δH on the head, inducing a response voltage δV following the pattern of the bits. Adapted from Ref. 72, reproduced with permission (© 2008 AIP).
