Figure 2

The DC magnetic hysteresis curve m(H) of P-Ba122od at T = 20 K, with the onset field Hon and the peak field Hp of the SMP indicated by arrows. We associate the structural rhomb-to-square vortex phase transition with the “step-like” enhancement of ∣m∣ in increasing H, giving rise to an m(H) shoulder. The structural transition field HST has been taken at the local minimum of dm/dH (represented by a continuous line).
