概要
- 論文の詳細を見る
The fully mapped T-H (temperature-magnetic field) phase diagram of DyNi_2Si_2 has been determined by heat capacity and magnetic susceptibility measurements. In zero magnetic fields, the heat capacity exhibits a small but distinct cusp at T_1 = 3.7 K corresponding to the magnetic order-order phase transition, and a clear λ-type transition at T_N=5.6K. Except for the paramagnetic phase, three magnetic phases are found below T_N and below the critical field H_c = 21.5 kOe. The results are discussed in comparison with recent experimental evidence which indicates the two-dimensionally modulated spin structures in the c-plane.
