From: No interface energy barrier and increased surface pinning in low temperature baked niobium
Hysteresis loop for the 120 \(^{\circ }\)C baked ellipsoid. The initial increase and decrease in the externally applied field is known as the virgin curve, shown in blue. The positive and negative moment used to determine pinning strength are shown in red and black. The standardisation curve used to determine H\(_{vp}\) is shown in the bottom left quadrant, which is determined using the virgin curve. The last point within error of 1 is taken as H\(_{vp}\).
