| 520 | _ | _ | |a 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. |
