Effects of perimeters of induced shielding current loops (ISCL) on a levitation force have been investigated for a single-domain YBa[sub 2]Cu[sub 3]O[sub 7-x] sample. The sample was prepared by a top-seeded melt–growth process. The levitation force of the sample decreases monotonously with the increasing perimeters of ISCL while the depth of the cutting slot increases along its diameter from one side to another. The maximum levitation force of the sample without any cutting slot is about 1.68 times higher than that of the sample bisected. A simple physical model is afforded to interpret the experimental results. © 2001 American Institute of Physics.
