Notes:
The voltage dependence of dc resistance of polycrystalline GdtY3−tFe5O12 (t=1.0, 1.1, 1.6, and 2.2) is experimentally studied at different temperatures. The data is explained on the basis of Krausse's theory. It is found that gadolinium substitution in YIG does not affect the grain-boundary potential barrier height (φ0). The temperature, however, affects φ0. The parameter z, in Krausse's model, which is found to be temperature independent, increases with the increase in the gadolinium substitution in YIG.
