Figure 1: Hysteretic magnetization data from an unpatterned PSV multilayer structure.
From: Hybrid superconducting-magnetic memory device using competing order parameters
The multilayer structure is Nb(100 nm)/Cu(3 nm)/Ni0.7Fe0.17Nb0.13(2.1 nm)/Cu(5 nm)/Ni(3 nm)/Cu(3 nm)/Nb(70 nm). The measurement temperature is 10 K. The field was swept from positive to negative (blue circles), then back to positive (red circles), as indicated by the coloured arrows. Illustrated above the plot are the different magnetization states (P: parallel; AP: antiparallel) of the Ni and Ni0.7Fe0.17Nb0.13 for the trace with the blue circles. Inset: Trend of Ni0.7Fe0.17Nb0.13 saturation magnetization with Nb doping.
