Magnetism and charge density waves in RNiC${}_2$ (R = Ce, Pr, Nd)

Abstract

We have compared the magnetic, transport, galvanomagnetic and specific heat properties of CeNiC${}_2$, PrNiC${}_2$ and NdNiC${}_2$ to study the interplay between charge density waves and magnetism in these compounds. The negative magnetoresistance in NdNiC${}_2$ is discussed in terms of the partial destruction of charge density waves and an irreversible phase transition stabilized by the field induced ferromagnetic transformation is reported. For PrNiC${}_2$ we demonstrate that the magnetic field initially weakens the CDW state, due to the Zeeman splitting of conduction bands. However, the Fermi surface nesting is enhanced at a temperature related to the magnetic anomaly.
