Yy. Tomashpolskii et al., MEASUREMENTS OF THE SECONDARY-ELECTRON EMISSION OF SUPERCONDUCTING TRANSITIONS AT HELIUM TEMPERATURES BY SCANNING ELECTRON-MICROSCOPY, Industrial laboratory, 61(1), 1995, pp. 23-25
For the first time the abrupt minimum of the SEE yield from a Bi-Sr-Ca
-Cu-O ceramic was observed in the vicinity of the superconducting tran
sition. After proper metrological testing, this effect can be used as
a basis for a new, sensitive, contactless method for determining a sup
erconducting transition that is local in area and depth.
