The magnetization of purposefully fabricated high-temperature superconductor (HTS) ceramic bulks can result in "superconductor permanent magnets" (SPMs). A pulse generator has been designed and built for this purpose. Series of HTS bulks with different compositions have been prepared by liquid phase sintering technique: The basic composition was YBa1.595Cu2.405Oy, which has been doped by Ca and/or Pt. The samples have been magnetized in Field Cooled (FC) and Zero Field Cooled (ZFC) modes at a maximum flux density of 0.2 T at liquid nitrogen temperature. The measurements proved that the average field trapping ability of the bulk with the composition of Y0.95Ca0.05Ba1.595Cu2.405 Oy is the highest among the tested samples.
