Estimation of generated heat in pulse field magnetizing for SmBaCuO bulk superconductor
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 Δ T max and specific heat C( T). Five successive magnetic pulses with a fixed amplitude ( B ex=3.01 T∼5.42 T) are applied and Δ T max a...

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