Hi Victor,

in the 1990s, I was involved with similar work in the context of a
superconducting MRI receive coil *. To avoid the losses of the capacitors
and the connections, we used a self resonant double-spiral design, using the
LaAlO3 substate as a high-Q dielectric. At 8.25 MHz, Q-factors of up to
500000 were achieved.

Best regards,
Markus (DF6NM)
