Contrasting c-axis and in-plane uniaxial stress effects on superconductivity and stripe order in La1.885Ba0.115CuO4

Principles of the μSR technique

In a μSR experiment (see the Supplementary Note 1 and the Supplementary Fig. S1), a high-intensity beam of 100% spin-polarized positive muons is directed into the sample, where the muons thermalize at…
