  Andreev molecules consist of two coherently coupled Josephson junctions and
permit non-local control over supercurrents. By making the barriers magnetic
and thus creating a spin-valve, we predict that a non-local Josephson diode
effect occurs that is switchable via the magnetic configuration of the
barriers. The diode effect is turned on, off, or changes its sign depending on
whether the spin-valve is in a parallel, normal, or antiparallel configuration.
These results offer a way to exert complete control over a non-local Josephson
diode effect via the spin degree of freedom rather than varying a global
magnetic flux which affects the entire system and likely neighbouring
components in a device architecture.
