Influence of sample geometry on determination of magnetocaloric effect for Gd60Co30Al10 glassy ribbons using direct and indirect methods

► Direct measurement of the adiabatic temperature change. ► Magnetic field induced entropy change by application of the Maxwell relation. ► Measuring the total heat capacity Cp(H,T) in zero and non-zero magnetic field. ► Two-dimensionality of the ribbon pieces causes strong internal demagnetizing fields. ► Important when evaluating the intrinsic MCE parameters from different methods.
