... varied both the temperature of the superconductor and the external magnetic field in the region of the sample, and we measured the magnetic field just above the surface of the Vanadium sample (Fig. 2). To create these plots, note that the Hall bar outputs a voltage signal, which we then anti-symmetrized then multiplied by the hall coefficient to deduce the magnetic field at the Hall bar. Further details on how the hall voltage is processed to obtain the magnetic field being observed by the hall bar is contained in the appendices. ...

... this, we get that a 1 = B c1 (0) = 0.091T and a 2 = B c2 (0) = 0.216T . Using this, we produced a phase diagram for our Vanadium sample (Figure 2). ...

... applied indium seal (0.06 milli-inch diameter wire) to the groove in the vacuum chamber ( Fig. D.2), then placed the vacuum chamber on the lid, and secured the vacuum chamber to the lid (with the sample inside) using 4-40 brass screws in a star pattern procedure to ensure uniform compression of the indium ...

... short wires within the same twisted pair on opposite sides of the PCB corresponding to I + /I − and V + /V − . Take extra precaution in strain relieving these connections since this is likely where wires will break during the cooling process (as shown in Figure E.2), if any. Solder male connectors on the end of these short wires, and attach to the remaining female connectors once completed. ...
