a bottom magnetic core piece positioned over and
contacting the first non-magnetic seedlayer;
a second non-magnetic seedlayer;
a top magnetic core piece positioned over and

a gap comprising a non-magnetic material
sandwiched
between at least a portion of the bottom core
piece and at least a portion of the second
