Abstract
A magnetoconductometric effect was found under pulsed magnetic action (B = 0.1–1 T) on a single crystal of the superionic conductor Pb0.67Cd0.33F2 (cubic symmetry, space group Fm¯3m, unit cell parameter a = 5.7575 A). The static electrical conductivity σdc was determined from impedance spectra in the frequency range (5–5)×105 Hz. In the absence of magnetic influence (B = 0) the ionic conductivity of a superionic crystal is σdc = 1.4×10–4 S/cm. When applying a magnetic field (B = (0.1−1) T) it increases, reaching σdc = 9.5 10−4 S/cm and σdc(B)/σdc(0) = 6.8 at B = 1 T. The nature of the magnetoconductometric effect in the superionic Pb0.67Cd0.33F2 is discussed in connection with the features its atomic structure.
