概要
- 論文の詳細を見る
We have investigated magnetic properties of ErB_2C_2 which is an isostructural compound of the antiferroquadrupolar ordering materials, DyB_2C_2 and HoB_2C_2, by magnetisation and neutron diffraction measurements. ErB_2C_2 shows magnetic transitions at T_N = 15.9 K and T_t = 13.0 K. The magnetic structure of the ground state is a simple Ising-type antiferromagnetic one with a propagation vector of k = (1, 0, 0). The intermediate phase between T_N and T_t under zero magnetic field is a long range magnetic ordered state with a transverse sinusoidal modulation with a propagation vector of (1 + δ, δ, 0), where δ = 0.1120(2) which is nearly the same as that in phase IV in HoB_2C_2.
