Strongly enhanced critical current density in Fe-sheathed MgB2 tapes by stearic acid and stearate doping
Zhaoshun Gao, Yanwei Ma, Xianping Zhang +6
Fe-sheathed MgB2 tapes with cheap stearic acid, Mg stearate and Zn stearate doping were prepared through the in situ powder-in-tube method. It is found that Jc, Hirr, and Hc2 were…
