  We report the results of our detailed magnetotransport studies on single
crystals of the antiferromagnetic heavy-fermion superconductor
Ce$_3$PdIn$_{11}$. Electrical resistivity measurements, carried out in
different magnetic field orientations with respect to the crystallographic
axes, were mainly aimed to amass further insight about the magnetically ordered
state. The results manifest a clear metamagnetic transitions in the ordered
phase when the applied field is parallel to the tetragonal $c$ axis, while no
similar features are seen for the transverse direction, i.e., with the field
confined within the $ab$ plane. This finding elucidates the fact that the $c$
axis is the easy magnetic direction in this system. Based on the electrical
transport and heat capacity data obtained for Ce$_3$PdIn$_{11}$, magnetic field
-- temperature phase diagrams were constructed, which elucidate fairly
enigmatic behaviors in this material featuring the existence of both second-
and first-order magnetic phase transitions.
