N2 - The temperature rises ΔT(t) of cryo-cooled SmBaCuO bulk superconductor have been measured after applying the pulse magnetic field from B ex = 3.01 to 5.42 T for various initial stage temperatures (T s = 40 K ∼ 70 K). For each T s and B ex the observed systematic change of ΔT and the trapped magnetic field B T can be explained in terms of the diagram of the maximum temperature measured at the bulk center surface (T0 max) vs. B T. The maximum temperature rise ΔT max decreases with increasing T s under the identical B ex.
