By making full use of an excellent trapped field performance of the c-axis
oriented single-domain Ag-bearing Sm123 superconductors with a diameter of
36 mm, we have developed several superconducting permanent magnet systems d
riven by static and pulsed fields. The Sm123 superconductor can trap a magn
etic field of 2.1 at 77 K and can increase its maximum trapped field to 9 T
at 25 K in the static field cooling magnetization. A Nd-Fe-B plate (50 x 5
0 x 5 mm(3)) can be magnetized to the same level as that due to the uniform
static magnetization by scanning it over the Sm123 superconducting permane
nt magnet. The construction of a pulse field-driven face-to-face-type magne
tic field generator capable of producing 1.8 T in an open space with a gap
of 12 mm is also presented. We also suggest hollowed Sm123 superconductors
to serve as a permanent magnet providing a uniform magnetic field exceeding
2 T over the range up to 10 mm.
