Field induced suppression of charge density wave in GdNiC${}_2$

Abstract

We report the specific heat, magnetic, magnetotransport and galvanomagnetic properties of polycrystalline GdNiC${}_2$. In the intermediate temperature region above $T_N$ = 20 K, we observe large negative magnetoresistance due to Zeeman splitting of the electronic bands and partial destruction of a charge density wave ground state. Our magnetoresistance and Hall measurements show that at low temperatures a magnetic field induced transformation from antiferromagnetic order to a metamagnetic phase results in the partial suppression of the CDW.
