THE THEORY OF THE MEASUREMENT OF THE LONDON PENETRATION DEPTH IN UNIAXIAL TYPE-II SUPERCONDUCTORS BY MUON SPIN ROTATION

Journal article

The effect of anisotropy on the measurement, by muon spin rotation, of the London penetration depth in the high-Tc uniaxial type II superconductors is considered in detail. Expression are derived which will allow the principal penetration depths, λ1 (λ⊥) and λ2 (λ|), to be determined using meas urements of the μSR line width from single crystals. For polycrystalline, powder or sintered, samples an expression is derived which will allow an effective penetration depth, λeff, to be determined from the measured μSR line width. Further, it is shown that for all anisotropy ratios, λ2/λ1, greater than five λ1∼0.81λeff. © 1988.
