...Has anyone every produced an airplane using the magnus effect? If the
cylinder is rotating faster, I would expect that lift would be increased.
Does anyone know if there have been any writings and/or test aircraft?

Doesn't count as a real aircraft, but a Magnus effect vehicle was theorized
in the 1957 juvenile science fiction book Tom Swift and his Ultrasonic
Cycloplane:

In the late 1970s the Van Dusen Development Company built a
subscale prototype rigid airship which rotated to produce lift
via the Magnus effect. They never built a full scale vehicle.
