Patel, A and Hopkins, SC and Giunchi, G and Albisetti, AF and Shi, Y and Palka, R and Cardwell, DA and Glowacki, BA (2013) The use of an MgB2 hollow cylinder and pulse magnetized (RE)BCO bulk for magnetic levitation applications. IEEE Transactions on Applied Superconductivity, 23. ISSN 1051-8223Full text not available from this repository.
Both MgB2 and (RE)BCO bulk materials can provide a highly compact source of magnetic field when magnetized. The properties of these materials when magnetized by a pulsed field are potentially useful for a number of applications, including magnetic levitation. This paper reports on pulsed field magnetization of single 25 mm diameter (RE)BCO bulks using a recently constructed pulse magnetization facility, which allows an automated sequence of pulses to be delivered. The facility allows measurement of force between a magnetized (RE)BCO bulk and a bulk MgB2 hollow cylinder, which is field cooled in the field of the magnetized (RE)BCO bulk. Hysteresis cycling behavior for small displacement is also measured to extract the stiffness value. The levitation forces up to 500 N were obtained, the highest ever measured between two bulks and proves the concept of a bulk-bulk superconducting bearing design. © 2002-2011 IEEE.
