  We demonstrate a Josephson junction with a weak link containing two
ferromagnets, with perpendicular magnetic anisotropy and independent switching
fields in which the critical current can be set by the mutual orientation of
the two layers. Such pseudospin-valve Josephson junctions are a candidate
cryogenic memory in an all superconducting computational scheme. Here, we use
Pt/Co/Pt/CoB/Pt as the weak link of the junction with $d_\text{Co} = 0.6$ nm,
$d_\text{CoB} = 0.3$ nm, and $d_\text{Pt} = 5$ nm and obtain a $60\%$ change in
the critical current for the two magnetization configurations of the
pseudospin-valve. Ferromagnets with perpendicular magnetic anisotropy have
advantages over magnetization in-plane systems which have been exclusively
considered to this point, as in principle the magnetization and magnetic
switching of layers in the junction should not affect the in-plane magnetic
flux.
