  We present a systematic study of the dc-resistivity, Hall effect, and
magnetoresistance in the normal state of quasi 2D heavy fermion superconductors
CeMIn5 (M: Rh and Co) under pressure. Here the electronic system evolves with
pressure from an antiferromagnetic (AF) metal, through a highly unconventional
non-Fermi liquid, and finally into a Fermi-liquid state. The amplitude of the
Hall coefficient increases dramatically with decreasing T, reaching at low
temperatures a value significantly larger than 1/ne. Furthermore, the
magnetoresistance is characterized by T- and H-dependence which clearly violate
Kohler's rule. We found that the Hall angle cot\Theta varies as T^2, and the
magnetoresistance is well scaled by the Hall angle as \Delta
\rho_{xx}/\rho_{xx}\propto \tan^2\Theta. These non-Fermi liquid properties in
the electron transport are remarkably pronounced when the AF fluctuations are
enhanced in the vicinity of the QCP. We lay particular emphasis on the striking
resemblance of these anomalous magnetotransport with those of the high-Tc
cuprates. We argue that features commonly observed in quasi 2D heavy fermion
and cuprates very likely capture universal features of strongly correlated
electron systems.
