Abstract

Magnetic susceptibility, specific heat, nuclear magnetic resonance and neutron diffraction measurements have been made to investigate the magnetic property of a ternary compound CeNiC₂. Temperature variations of magnetic susceptibility and specific heat suggest that magnetic transitions take place at T = 20 K, 10 K and at 2.2 K. NMR line width of ¹³C nuclei increases remarkably below T = 20 K indicating the increase of transferred hyperfine field due to magnetic order. In the neutron diffraction pattern below T = 20 K, additional peaks appear which indicate the presence of long-range magnetic order. Based on these measurements, a magnetic structure model of CeNiC₂ which involves a transition from an incommensurate to a commensurate anti-ferromagnetic order is presented.
