Title: Magnetic and transport behaviors of non-centrosymmetric Nd 7Ni 2Pd

Abstract

Crystallographic, magnetic, electrical transport and thermodynamic properties of pseudo-binary Nd 7Ni 2Pd compound have been studied using temperature-dependent x-ray powder diffraction and physical property measurements. Compared to the ferromagnetic parent Nd 7Pd 3, the ground state of Nd 7Ni 2Pd is antiferromagnetic, and it exhibits strong metamagnetism. The measurements indicate two antiferromagnetic transitions in fields less than 8 kOe: a second-order paramagnetic to antiferromagnetic at T N2 = 29 K and a weak first-order antiferromagnetic to antiferromagnetic transition at T N1 = 24.5 K. Here, the compound becomes ferromagnetic in fields of 8 kOe and higher with T C = 30 K. Temperature dependence of lattice parameters is anomalous, most prominently in the basal plane at ~30 K; however, there is no detectable structural distortion or clear volume discontinuity around 25 K, suggesting a significant weakening of the first-order transition when compared to the binary Nd 7Pd 3.
