The apparatus further comprises a ferrimagnetic structure comprising a first portion disposed under the first coupler, a second portion disposed under the second coupler, and a gap defined between the first coupler and the second coupler, the gap physically separating the first portion from the second portion. One or both of the first portion and the second portion comprises a first plurality of ferrimagnetic strips interleaved with a second plurality of ferrimagnetic strips configured to attenuate a magnetic flux passing between the first and second couplers. The first plurality of ferrimagnetic strips are interleaved with the second plurality of ferrimagnetic strips under at least a portion of the first coupler that is overlapped by the third coupler.
