Study of Unconventional Slow Critical Dynamics of the Frustrated Magnet DyRu2Si2 ~Spontaneous Alignment of Emergent Ferromagnetic Spin Textures?~
2023-10-17
We measured the ac susceptibility of the frustrated magnet DyRu2Si2, in the partially ordered phase, where emergent 2-dimensional (2-D) disordered planes appear, and revealed extraordinarily slow and unconventional dynamics, which could be attributed to the highly fluctuating nature of the emergent 2-D planes.
