We show that this coil with core of specific design is capable of creating fields of at least several tens of milliTeslas in a small region (100µm cubic) at low current. We also provide our acquiring of the relative magnetic permeability of metallic glass 2605SA1 and conclude that this material is sufficiently magnetizable at milliKelvin temperatures to be used as transformer cores in dilution refrigerators. Furthermore, we show how the persistent current switch we built is capable of holding a superconducting current loop with a lifetime of at least several minutes.Show less
