Abstract
The trapped field B T P = 5.20 T has been realized on the GdBaCuO bulk superconductor by a modified multi pulse technique combined with a stepwise cooling (MMPSC), which surpassed the previous highest record of B T P = 4.47 T. At the first stage, a small amount of the magnetic field ∼1 T was trapped at the bulk center with a concave field distribution at a high starting temperature T s ∼ 45 K by the low pulse field application B ex ∼ 4.5 T. Following the first stage, the higher field of B ex ∼ 6.7 T was applied at a lower T s ∼ 30 K at the second stage. The concave trapped field profile over the bulk at the first stage and the optimization of the higher applied pulse field at the second stage are key points to enhance B T above 5 T.
