摘要: The magnetocaloric response of an ensemble oriented uniaxial magnetic objects, perpendicularly magnetized to their easy axes, for temperatures close the blocking temperature is calculated with aim demonstrating that control sample's microstructure makes up effective way tailor its response. Coexisting positive and negative effect (MCE) found a model material single phase transition. Both MCE regimes are controlled by magnitude applied field. As proof concept, experimental results arrays self-assembled ferromagnetic nanowires embedded into highly ordered nanoporous anodic alumina templates shown, suggesting validity numerical calculations.
