  The lengthscale over which supercurrent from conventional BCS, $s$-wave,
superconductors ($S$) can penetrate an adjacent ferromagnetic ($F$) layer
depends on the ability to convert singlet Cooper pairs into triplet Cooper
pairs. Spin aligned triplet Cooper pairs are not dephased by the ferromagnetic
exchange interaction, and can thus penetrate an $F$ layer over much longer
distances than singlet Cooper pairs. These triplet Cooper pairs carry a
dissipationless spin current and are the fundamental building block for the
fledgling field of superspintronics. Singlet-triplet conversion by
inhomogeneous magnetism is well established. Here, we describe an attempt to
use spin orbit coupling as a new mechanism to mediate singlet-triplet
conversion in $S-F-S$ Josephson junctions. We report that the addition of thin
Pt spin-orbit coupling layers in our Josephson junctions significantly
increases supercurrent transmission, however the decay length of the
supercurrent is not found to increase. We attribute the increased supercurrent
transmission to Pt acting as a buffer layer to improve the growth of the Co $F$
layer.
