Transport Properties Above Tc


Magnetotransport properties in Nd\(_{2-x}\)Ce\(_{x}\)CuO\(_{4}\), and La\(_{2-x}\)Sr\(_{x}\)CuO\(_{4}\) above \(T_{c}\) show unusual behaviors with respect to the temperature (T)-and doping concentration (x)-dependence. The resistivity \(\rho\) in optimum (highest \(T_{c}\)) samples shows a T-linear behavior while that in highly overdoped samples exhibits a T-quadratic behavior.
