Özet

Magnesium diboride (MgB 2) is a good alternative for some of the conventional superconductors due to its low raw material costs and to its relatively simple production process. MgB 2 wires have also been considered for AC applications. In this work, we present the magnetization AC loss results of a Ti-sheathed monofilament MgB 2 wire when magnetic fields are applied perpendicular to the wire axis. Losses were measured by the calibration-free method using a lock-in amplifier at 144 Hz and also investigated theoretically in the same condition. Numerically estimated losses were compared to measured values. © Springer Science+Business Media, LLC 2010.
