Spin-cluster excitations in the rare-earth kagome systemNd3Ga5SiO14

High-field magnetization and ESR in the triangular-lattice antiferromagnets Ba3MnSb2O9 and Ba3TNb2O9 (T=Ni, Co)

“…Thus, these EPR modes above T N1 are quite different from the conventional EPR modes of a paramagnet. They could be ascribed to the excitations of short-range correlated spin clusters as illustrated in the rareearth kagome system Nd 3 Ga 5 SiO 14 [29]. To further clarify this point, ESR measurements of high-quality single crystal are desired.…”

Ordered ground states of kagome magnets with generic exchange anisotropy

“…We have used numerical calculations to determine the full zero temperature phase diagram of the most general anisotropic nearest-neighbor exchange model, showing the extent of these five phases [Figs. [8][9][10][11][12][13][14][15]. One of the five phases (E-noncoplanar 12 ) is found to be exceedingly rare in the parameter space [Fig.…”

“…Appendix A: Numerical optimization of energies Here we describe the numerical optimization used to obtain the phase diagrams in Figs. [8][9][10][11][12][13][14][15] and the estimates of the relative frequency of phases in Fig. 7.…”

“…Kagome lattice rare-earth materials [10][11][12][13][14][15][16][17][18][19][20] provide a realization of this scenario. The kagome lattice [Fig.…”

Local evidence for collective spin excitations in the distorted kagome antiferromagnet Pr$_3$BWO$_9$

“…In another distorted kagome system Nd 3 Ga 5 SiO 14 and Pr 3 Ga 5 SiO 14 , electron spin resonance study have revealed the collective spin excitations instead of the longrange continuum [29,30]. In Pr 3 Ga 5 SiO 14 , Dynamical short-range ordering is suggested from diffuse neutronscattering observations [21] .…”
