Various sample designs prepared to investigate the influence of the microstructure shape on the transition. Scale bars, 50 μm. Different types of sample designs from the U-shaped sample mainly shown in the manuscript, to thick and wide slabs, to thin, spring-like meander designs were fabricated. Two of them, CeRhIn5_#7 and CeRhIn5_H3 were mounted on epoxy glue, while the other two were not. These different types of mounting were used to check for the potential influence of strain originating from the differential thermal contraction. The consistent observation of Shubnikov–de Haas oscillations in the samples rules out significant strain, as inhomogeneous pressure smears out the frequencies and prevents their observation. All studied samples show the DW transition in quantitative agreement, regardless of the sample shape.
