Description

We have measured the electrical resistivity from 10-300 K of two nominally identical samples of (Nd1.6Sr0.4)NiO4+δ. Both samples display clear semiconductor-like behaviour down to ∼70 K. Below there are a series of transitional effects associated with metallic and magnetic behaviour. Since both samples are in the critical range where the tetragonal structure is being stabilised the behaviour is sample dependent. It is shown that both magnetic and structural effects influence the thermal hysteresis present in the electrical resistivity below 70 K. (orig.)
