概要
- 論文の詳細を見る
Resonant magnetic x-ray diffraction experiments were carried out on the stacked triangular lattice antiferromagnet GdPd2Al3. The experiments revealed an expected initial collinear $c$-axis order at $T_{\text{N1}}$ followed by an additional in-plane order at $T_{\text{N2}}$, while at the same time we found that the ground state is a helically ordered state of a very long incommensurate period of approximately 700 Å. The distribution of K-domains was highly anisotropic, and the domain with the modulation vector normal to the surface of the crystal was ascendant. Low-field magnetization is discussed on the basis of the observed incommensurate magnetic structure.
