Spin-Gap Effect on Resistivity in the<i><i>t</i></i>-<i><i>J</i></i>Model
We calculate the spin-gap effect on dc resistivity in the t - J model of high- T c cuprates by using the Ginzburg-Landau theory coupled with a gauge field as its effective field theory to obtain \(\rho(T) \propto T \{ 1-c\:(T^{\ast} -T)^{d} \}\), where T * is the spin-gap onset …
