Fig. 1: Low-energy μSR setup for measurements on SRO214 single crystals.
From: Unveiling unconventional magnetism at the surface of Sr2RuO4
a SRO214 crystals cleaved and glued onto a Ni-coated aluminium plate to form a mosaic for the LE-μSR measurements. The scale bar corresponds to a length of 2 cm. b Experimental LE-μSR setup with applied field vector Bext perpendicular to the sample (i.e., along the c-axis of SRO214 coinciding with the axis z of our orthonormal reference-axes system) and arrays of positron detectors used to count muon decay events. The schematic cut-out allows viewing the sample inside the detectors. c LE-μSR measurement configurations for different orientations of the initial muon spin polarization vector Sμ+: Sμ+ perpendicular to the applied field vector Bext and precessing in the xy-plane of our reference-axes system as indicated by the shadowed red circle (transverse field, top) or Sμ+ collinear to Bext (longitudinal field or zero fields with Bext = 0, bottom). d Muon implantation profiles in SRO214 simulated for a few representative implantation energies.
