Fig. 4: Switching probabilities as a function of tip location and input length compared to calculations.
From: Remote detection and recording of atomic-scale spin dynamics
a Closed circles: switching probabilities PH and PU as a function of tip location for nin = 3 (10 mV, 2 pA, 550 ms). Open circles: values averaged over the first 20 ps from c. Note the different axes used for open and closed circles. b Same as a but for nin = 5 (10 mV, 1.6 pA, 100ms). c Time-dependent Schrödinger equation calculations performed on an Fe trimer. The curves show the time evolution of the expectation value of Sz at atom A following a single excitation on each of the input atoms. d Same as c but for an Fe pentamer. e PH as a function of tip location for nin = 9. Different curves correspond to different tip heights: 180 pm (420 fA), 80 pm (4.3 pA) and 30 pm (15.2 pA) for, respectively, light blue, dark blue and magenta. All voltage pulses last 300 ms at 10 mV. The gray curve is taken at 180 pm, 1 mV, for reference. Data in a, b, e are taken at 1.5 K, 1 T. The error bars show 1.5σ for a binomial distribution with μ at the recorded rate. Dashed lines are guides to the eye.
