We investigate the normal-state transport properties of
and we show that a consistent explanation of the
experimental results can be obtained assuming that the system is
near a quantum phase transition. Within the framework of a
self-consistent spin fluctuation theory, we calculate the
temperature variation of some relevant physical quantities and we
discuss a possible microscopic origin of the quantum phase
transition.
