A lattice volume of the main phase is 0.830 nm3 to 0.840 nm3, and a density of the main phase is 7.70 g/cm3 to 8.00 g/cm3.

Abstract: Provided is a circular pole piece that contributes to simplification of work and a reduction in costs and that has no gap created among adjoining blocks. A circular pole piece is manufactured by circularly arranging laminate blocks each having numerous hexagonal directional magnetic steel sheet tiles layered. Since heteromorphic soft magnetic material tiles are unnecessary, work can be simplified and the cost of the circular pole piece can be reduced. Moreover, the laminate blocks can be arranged substantially circularly without a gap among adjoining blocks.

Abstract: The temperature of permanent magnet blocks embedded in several positions in permanent magnets and base yokes will be adjusted by device of a heater to improve the static field uniformity.

Abstract: For the purpose of always keeping the positional relationship fixed between a support section for supporting a supported object and a base section for receiving the support section, the present apparatus comprises: a support section 500 for horizontally supporting a supported object; a base section 112 having a horizontal plane on its top; and a position adjusting section 300 provided between the support section and the base section, for moving the support section forward/backward between a position above the horizontal plane and a position off the horizontal plane while keeping the support section at a level higher than the horizontal plane, and for moving the support section upward/downward between a position higher than the horizontal plane and a position lower than the horizontal plane at the position off the horizontal plane.
