Fig. 3: Temperature Dependence of Antiferromagnetism on GdTe3.
From: Atomic-scale visualization of a cascade of magnetic orders in the layered antiferromagnet GdTe3
a–d FTs of AFM Fourier peaks from Cr tip scans at VBias = -400 mV, ISet = 60 pA on GdTe3 (topographies shown in Supplementary Fig. 14) show strong peaks at 4.4 K, a weaker peak at 6.7 K, and the absence of AFM peaks when heated to 7.9 K and above; cooling back down shows clear AFM peaks at 4.7 K. The displayed FTs have been first nearest-neighbor averaged. e–g Inverse FTs of Bragg and AFM peaks from a to c show the decay of the magnetic order upon heating; the AFM Fourier intensity was multiplied by 5 to show the contrast more clearly. h Plot of the temperature dependence of AFM Fourier peak intensity, normalized to the maximum intensity value. The blue curve is a guide to the eye. The light gray line is a measure of the error given by the average background intensity level, with its thickness corresponding to the standard deviation of the background Fourier intensity.
