抄録

A linear chain antiferromagnet CuCl₂2NC₅H₅ was investigated by antiferromagnetic resonance methods. The shift of resonance point due to three-dimensional ordering was observed from 2 K to 0.6 K aroung T_N=1.14 K. The antiferromagnetic principal axes in ac-plane decline by 8° from the paramagnetic principal axes and it was explained by introducing an anisotropic exchange interaction (A) in addition to the dipole interaction (B) as A⁄B=2.3. The observed antiferromagnetic resonance modes were satisfactorily explained by assuming two sublattices with the orthorhombic anisotropy, K₁β²⁺K₂γ² with the anisotripic constants of K₁=60 ergs/cm³ and K₂=210 ergs/cm³, and the Dzialoshinski-Moriya interaction with D-vector along a spin easy axis which is in the direction declined by 22° from a- to c-axes.
