Yes, I was also assuming MEG by a MEMS-fabbed array of e.g. rubidium vapor
atomic magnetometers at RT. I presume the paper I was asking for
(really no IEEE members here?)
was about that.

Cryogenic SQIDs just don't work in a portable setting.

As far as I can see, an array of NEMS atomic magnetometers would
very nicely fit into a skullcap, requiring no particular shielding
or power requirements below what's available for mobile applications.
