Özet
We produced RE-123 infiltrated by Sm123 superconductors by the melt growth method. The samples have been investigated in terms of X-ray diffraction (XRD)analysis, AC susceptibility, levitation force, and a magnetic stiffness calculation. The X-ray diffraction analysis showed that the Sm123 and Y123 phases were insufficiently grown at the selected sintering temperature of 1040 °C. The transition temperature of the IP Sample is 94.28 K from the AC Susceptibility (at 1 KHz and 4 Oe applied AC field)measurement. The magnetic stiffness was calculated using our newly designed vertical magnetic levitation force measurement system. It has a Nb-Fe-B permanent magnet (~0.5T)at 77 K with the Zero Field Cooled process. The magnetic stiffness was calculated using the data of the levitation force. The descending experimental results showed that the most significant F 0 was contained in the sample I5 (F 0 = 9.034 N)and the largest constant b value was determined in the sample IP (b = 0.3320 mm -1 ). But in the ascending results, the most significant F 0 is 8.604 N, and the largest constant b is 0.3047 mm -1 , both calculated in the IP sample. Considering the oxygen content effects on the magnetic stiffness, one can infer that it has been positively affected by an increase in the Sm123 infiltration. These results indicatethat the produced samples could be applied to bearing systems, magnetic sensors and other technological applications. © 2019 The Physical Society of the Republic of China (Taiwan)
