Extended Data Fig. 3: Spatial studies of diamagnetism in S2.
From: Imaging the Meissner effect in hydride superconductors using quantum sensors
We perform spatial studies of the local suppression in Bz in sample S2 along two orthogonal line cuts. Insets in (b) and (d) show fluorescence scans of S2 with the respective line cuts on top of the identified CeH9 region (enclosed in dotted yellow line). (a) The Bz values extracted from ODMR spectra are plotting against the applied external field, Hz, for six spatial points (indexed) along the line cut shown in inset of (b). (b) Similar to sample S1 [maintext Fig. 3(g)], we measure a spatially varying suppression in the local field suggesting the formation of ≈ 10 μm regions of CeH9 via laser heating. (c-d) A repeat of the study for six spatial points along an orthogonal line cut (inset of (d)).
