FIELD: instrumentation engineering. SUBSTANCE: invention is intended for design of pickups of various types and magnetic suspensions. Process involves mixing of powder of superconductive material YBa2Cu3O7-δ and polymer with subsequent pressing. Novelty of invention consists in usage of powder of polyvinylchloride in the amount of 10-20% of mass of manufactured composition in the capacity of polymer material. Pressing is conducted under pressure 96-140 MPa at temperature 433-453 K in the course of 5-25 min. EFFECT: enhanced efficiency of process. 1 tbl
