The normal-state Hall effect and magnetoresisitance (MR) have been measured in the quasi two dimensional (2D) heavy fermion superconductor CeCoIn5. In the non-Fermi liquid region where the reistivity rho(xx) exhibits an almost perfect T-linear dependence, the Hall angle varies as cot theta(H) proportional to T-2 and MR displays a strong violation of Kohler's rule. We demonstrate a novel relation between the MR and the Hall conductivity, Deltarho(xx)/rho(xx) proportional to (sigma(xy)rho(xx))(2). These results bear a striking resemblance to the normal-state properties of high-T-c cuprates, indicating universal transport properties in the presence of quasi-2D anti ferromagnetic fluctuations near a quantum critical point.
