Plots of MR of SmB₆ nanowire versus B, measured at different temperatures. The magnetic field is parallel to SmB₆ nanowire. The bias current is 0.1 μ A . (a) Schematic diagram of the nanowire device, (b) MR at 1.5 K without hysteresis behavior. (c)–(f) The MR values versus B at 4 K, 5 K, 6 K, and 7 K, respectively. The hysteresis behavior gradually becomes obvious.
