Influence of the demagnetizing field on the determination of the magnetocaloric effect from magnetization curves
(AIP Publishing, 2009-02-12)
The influence of the demagnetizing factor (N) on the magnetic entropy change (DSM) curves is studied for materials with a second order phase transition. For this purpose, a soft magnetic amorphous ribbon is measured for ...

Influence of Ge addition on the magnetocaloric effect of a Co-containing Nanopermtype alloy.
(AIP Publishing, 2008)
The influence of the partial substitution of B by Ge on the magnetocaloric response of Fe78Co5Zr6B10Cu1 is studied. Ge addition produces a reduction in the temperature at which the peak entropy change takes place, as ...
