      abstract     = {We present bulk and neutron scattering measurements
                      performed on the isotopically enriched 154Sm2Ti2O7 and
                      154Sm2Sn2O7 samples. Both compounds display sharp heat
                      capacity anomalies, at 350 and 440 mK, respectively.
                      Inelastic neutron scattering measurements are employed to
                      determine the crystalline electric field (CEF) level scheme,
                      which includes transitions between the ground-state and
                      first excited J multiplets of the Sm3+ ion. To further
                      validate those results, the single-ion magnetic
                      susceptibility of the compounds is calculated and compared
                      with the experimental dc-susceptibility measured in low
                      applied magnetic fields. It is demonstrated that the
                      inclusion of intermultiplet transitions in the CEF analysis
                      is fundamental to the understanding of the intermediate and,
                      more importantly, low-temperature magnetic behavior of the
                      Sm-based pyrochlores. Finally, the heat capacity anomaly is
                      shown to correspond to the onset of an all-in-all-out
                      long-range order in the stannate sample, while in the
                      titanate a dipolar long-range order can be only indirectly
                      inferred.},
