High-temperature superconductors (HTSC) have a significant potential for application in systems based on magnetic levitation. The wide spread of second-generation HTSC tapes (CC- tape from coated conductors) allows the use of stacks of CC-tapes as an alternative to bulk superconductors, particularly in levitation systems. The paper presents the results of research of CC-tapes of various manufacturers - SuNAM, THEVA and SuperOx. The tapes were cut into square 12 mm × 12 mm fragments and stacked in stacks, the number of tapes varying from 10 to 100. The measured dependences of the levitation force on the distance between the magnet and the stack have similar patterns for tapes of all manufacturers - the force of interaction increases with increasing thickness of stacks. However, the influence of the thickness of the stack on the levitation force for different CC-tapes is of a different nature.
