“…No other commercially available material offers these advantages. These advantages make it possible to study the general laws of electrodynamics in technical superconductors [Klimenko et al, 1997], which are almost not masked by specific features of particular samples. Experiments with niobium-titanium wires are not complicated by brittleness and high sensitivity to straining; those are typical features of intermetallic compounds and HTSC.…”

Various applications of superconducting materials require accounting of the critical current anisotropy relative to magnetic field direction - I c7(θ). However, today there is no sufficiently comprehensive model that takes into account the anisotropy, therefore the angular dependences are usually not analysed, but only described using various mathematical formulas. As a result, the fitting parameters have no physical meaning and it is difficult to correlate the picture with the features of the microstructure. In this paper, we propose a method for analysing the critical current angular dependences based on the anisotropic pinning model. The applicability of this model for conventional superconducting Nb-Ti tapes with one peak in the I c7(θ) dependence is shown. The possibility of extending this model to analyse the angular dependences of HTS materials is discussed.
