Abstract
We report a study on the structural and transport properties of long in situ MgB2/Fe wires that are prepared by use of amorphous boron and nano amorphous boron powders with 50-50% weight ratio. The wire samples are fabricated by means of a standard Powder-in-Tube (PIT) method. Transport measurements are applied under high magnetic fields, of up to 9 T, obtained in a Bitter magnet. We find that use of a mixture of the amorphous boron and amorphous nano boron precursor powders at equal amounts is very promising way to fabricate long wires without any degradation in transport engineering Jce values in the presence of low and moderate magnetic fields.
