The Nd-doped cuprate displays a first-order phase transition at (= 74 K for x=0.10, y = 0.60) to a low-temperature tetragonal (LTT) phase. A magnetic field applied the a-axis leads to an increase in , whereas is decreased when . 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.
