First, don't put such a cards on adjacent slots.
Second, if you have >0.7mm distance between adjacent cards, can put
shield between them: thin (max 0.1mm) metal (best copper) plate put
inside at least 0.3mm plastic (don't use too thin or too soft plastic:
its purpose is to protect electrically connected parts from touching
the plate, such a touching can cause computer damage!!!) and connected
electrically to ground (e.g. computer case). Note the metal plate must
be fixed firmly inside the plastic to make sure it will not touch any
computer part. It should have size slightly larger than card shielded
by it. This of course makes electrical shielding only, for magnetic
shielding need more place: 0.5mm (or more) iron plate + 0.1mm of copper,
all put inside plastic isolator (for safety), put around the card:

The magnetic shield must be made of one plate of magnetically soft iron.
I just looked into my PC and saw there is 2-5mm between cards, this is
a lot of space for shielding.
