      abstract     = {NdAl2 and TmAl2 single-crystals display Curie temperature
                      (TC) at 76.5 and 6.0 K, which are significantly close to
                      liquid nitrogen and helium (THe) temperatures, respectively.
                      Maximum entropy-change (−ΔSM) for 0–70 kOe are 35.9 and
                      8.9 J/kg-K at TC with large cooling efficiency 655 and 398
                      J/kg for TmAl2 and NdAl2, respectively. Adiabatic
                      temperature change at THe for 0–20 kOe is 3.7 K for TmAl2.
                      This is promising for cryogenic refrigeration down to
                      sub-Kelvin temperature using an electromagnet. The −ΔSM
                      for SmAl2 is low (∼0.5 J/kg-K at TC for 0–70 kOe). The
                      direction-dependent anisotropy in thermal and field
                      variations of ΔSM, and a reasonable correlation between
                      ΔSM and magnetoresistance are realized for NdAl2 and
                      TmAl2.},
