Abstract

The Nd-doped cuprate La_2-y-χNd_ySr_χCuO₄ displays a first-order phase transition at T_d (= 74 K for χ=0.10, y = 0.60) to a low-temperature tetragonal (LTT) phase. A magnetic field H applied ∥ the a-axis leads to an increase in T_d, whereas T_d is decreased when H ∥ c. The field couples to the LTO-LTT instability in an anisotropic way that is not understood. Related anisotropic effects are observed in the uniform susceptibility and the in-plane magnetoresistance.
