Giant magnetocaloric effect in antiferromagnetic ErRu2Si2 compound
T Samanta, I Das, S Banerjee - Applied Physics Letters, 2007 - pubs.aip.org
Giant magnetocaloric effect has been observed in Er Ru 2 Si 2, which is associated with
field-induced metamagnetic transition from antiferromagnetic to ferromagnetic state. The
maximum values of magnetic entropy change (− Δ SM max) and adiabatic temperature
change (Δ T ad max) for a field change of 7 T are evaluated to be 19.3 J∕ kg K and 15.9 K,
respectively, around 5.5 K within the temperature range of 4–25 K. The value of Δ T ad
max is even larger than other potential magnetic refrigerant materials reported in the same …
