RE: Mu Metal

Google led me to ad ad for Ultraperm, which said "The alloy contains 80.3% nickel, 14.3% iron and 5.4% molybdenum." I assume that Molyperm is the same thing. 20+ years ago we (Bottlhead) had a power supply transformer in a phono preamp that induced hum. The manufacturer resolved it with a copper flux band overlayed with a layer of molyperm tape.

I don't know which wrap was more effective, but together they worked well.
