      abstract     = {We report the magnetization, ac susceptibility, and
                      specific heat of optically float-zoned single crystals of
                      CePdAl3. In comparison to the properties of polycrystalline
                      CePdAl3 reported in the literature, which displays a
                      tetragonal crystal structure and no long-range magnetic
                      order, our single crystals exhibit an orthorhombic structure
                      (Cmcm) and antiferromagnetic order below a Néel temperature
                      T1=5.6 K. The specific heat at zero field shows two
                      anomalies, namely, a broad transition at T1=5.6 K followed
                      by a λ-anomaly at T2=5.4 K. A conservative estimate of the
                      Sommerfeld coefficient of the electronic specific heat,
                      γ=121mJK−2mol−1, indicates a moderately enhanced
                      heavy-fermion ground state. A twin microstructure evolves in
                      the family of planes spanned by the basal plane lattice
                      vectors ao and co , with the magnetic hard axis bo common to
                      all twins. The antiferromagnetic state is characterized by a
                      strong ao, co easy-plane magnetic anisotropy where the ao
                      direction is the easy axis in the easy plane. A spin-flop
                      transition induced under magnetic field along the easy
                      directions, results in complex magnetic phase diagrams.
                      Taken together, our results reveal a high sensitivity of the
                      magnetic and electronic properties of CePdAl3 to its
                      structural modifications.},
