Abstract

We report thermodynamic and neutron diffraction measurements on the magnetic ordering properties of the honeycomb lattice magnet YbCl₃. We find YbCl₃ exhibits a Neel type long-range magnetic order at the wavevector (0,0,0) below T_N = 600 mK. This magnetic order is associated with a small sharp peak in heat capacity and most magnetic entropy release occurs above the magnetic ordering temperature. The magnetic moment lies in-plane, parallel to the monoclinic a-axis, whose magnitude m_{YbY = 0.86(3) υ}dB^ is considerably smaller than the expected fully ordered moment of 2.24 υ_{B6 for the doublet crystal-field ground state. These results indicate the presence of strong quantum fluctuations in YbCl}d3^.
