Resumen:
powder-in-tube (PIT) MgB2 coils. The coils’ properties were measured bytransport and magnetization at different applied fields (H) and temperatures(T ). The engineering critical current (Je) value is the largest reported in PITMgB2 wires or tapes. At 25 K our champion six-layer coil was able togenerate a field of 1 T at zero external field (Ic > 220 A,Je ∼ 2.8 × 104 A cm−2). At 4 K this coil generated 1.6 T under an appliedfield of 1.25 T (Ic ∼ 350 A, Je ∼ 4.5 × 104 A cm−2). These magnetic fieldsare high enough for a superconducting transformer or magnet applicationssuch as MRI. An SiC doped MgB2 single layer coil shows a promisingimprovement at high fields and exhibits Jc > 104 A cm−2 at 7 T.
