<How long does core stay magnetized without power?

Years.

<How many bytes of battery-backed RAM are there in a typical PC?

Not a lot usually something in the 32-128byte range, maybe more.

<Haven't there been contemporary memory devices that use nano-scale
<cores, to eliminate the battery needs and radiation sensitivity of RAM?

Not that I'm aware of.
