摘要：
Making use of the inverse Wiedemann effect in non-magnetostrictive hairpin shaped metallic glass ribbons we have made flux-gate sensors with small dimensions (d × l = 3 × 8 mm2) and RMS noise levels of 2 nT (0.02-1 Hz). The inverse Wiedemann effect arises from a helical anisotropy induced by torsional stress annealing. © 1990.
