Abstract
We have measured the electrical resistivity from 10-300 K of two nomin ally identical samples of (Nd1.6Sr0.4)NiO4+delta. Both samples display clear semiconductor-like behaviour down to approximately 70 K. Below there are a series of transitional effects associated with metallic an d magnetic behaviour. Since both samples are in the critical range whe re the tetragonal structure is being stabilised the behaviour is sampl e dependent. It is shown that both magnetic and structural effects inf luence the thermal hysteresis present in the electrical resistivity be low 70 K.
