(a) Temperature dependences of the 𝜇SR relaxation rate 𝜎_𝑎∝𝜆_𝑎⁻²,𝜎_𝑏∝𝜆_𝑏⁻², and 𝜎_𝑐∝𝜆_𝑐⁻² of single crystals of YBa₂Cu₄O₈ measured along the three principal crystallographic axes 𝑎, 𝑏, 𝑐. (b) Temperature dependence of the 𝜇SR relaxation rate 𝜎_𝑎∝𝜆_𝑎⁻²,𝜎_𝑏∝𝜆_𝑏⁻², and 𝜎_𝑐∝𝜆_𝑐⁻² of single crystals of YBa₂Cu₃O_7−𝛿 measured along the three principal crystallographic axes 𝑎, 𝑏, 𝑐. The lines in (a) and (b) are results from model calculations as discussed in [22–25], after [22–25].
