Figure 4

Relaxation parameters. The normalized parameters N as a function of temperature in the (a,b) SNO/LAO and (c,d) SNO/LSAT films. In (a,c), symbols and solid curves show the normalized relaxation exponent s_N and the negative normalized activation energy – E_AN, correspondingly. In (b,d), symbols and solid curves show the normalized relaxation coefficient lnA_N and the normalized activation energy E_AN, correspondingly.
