Abstract

The generated heat Q during the pulse field magnetizing (PFM) has been estimated for a cryo-cooled SmBaCuO bulk superconductor based on the maximum temperature rise ΔTmax and specific heat C(T). Five successive magnetic pulses with a fixed amplitude (Bex=3.01 T ∼ 5.42 T) are applied and ΔTmax are measured for the various initial temperature Ts between 40 and 70 K. Q has shown characteristic dependences on Ts,Bex and the pulse number of the successive pulses. The pinning loss (Qp) and viscous loss (Q v) have been separated and estimated as a function of Ts and Bex.
