Li & Torr's 1992 Physical Review B paper is a theoretical model of superconductor magnetic permeability, not a claim that rotating ions generate a usable antigravity field

Ning Li and Douglas Torr's "Gravitational effects on the magnetic attenuation of superconductors" (Physical Review B 46(9): 5489–5495, received 12 March 1992, published 1 September 1992) was read in full from a scanned reprint. Its actual subject is relating a superconductor's two "historical independent traditional hallmarks" — perfect conductivity and perfect diamagnetism — through a theoretical model, concluding only that "[o]ur result suggests a possible importance of gravitational effects in understanding superconductivity." The words "antigravity," "usable," "propulsion," and "application" do not appear anywhere in the paper. It does contain a generative mechanism internally — lattice ions acquiring angular momentum from the superconducting condensate's magnetic field, driving "an induced precession" until "a time-dependent gravitomagnetic field[] is generated within the superconductor" — but that field is internal and self-consistent, invoked to explain the superconductor's own anomalously poor Meissner effect, not framed as an externally usable force.

This directly narrows the vault's existing finding that the pair's 1991 Physical Review D paper is also a passive calculation, not the "generator" claim a Tier-4 secondary summary once attributed to their work overall. Two papers into the series, the active "rotating ions generate a usable field" claim still has not been located in either journal paper — see where it actually surfaces.
