Claims

C1strongest claim

These results demonstrate that the combination of Co doping and controlled nanostructuring effectively optimizes the magnetocaloric response, with a maximum entropy change of 1.13 J/(kg K) under 3 T for x=1.

C2weakest assumption

That the Maxwell relations applied to the measured magnetization curves give an accurate entropy change without significant contributions from particle-size effects or undetected secondary phases in the nanostructured samples.

C3one line summary

Cobalt substitution in these nanostructured perovskites increases ferromagnetic coupling and produces a maximum magnetic entropy change of 1.13 J/kg K under 3 T for the x=1 composition.
