Investigation of complex magnetic structure and the role of frustration using neutron diffraction study in CeRh1-xPdxSn

Abstract: The quasi-kagome Kondo lattice CeRhSn exhibits intrinsic quantum criticality induced by geometrical frustration. Divergent Grüneisen ratios provide evidence for a zero-field QCP. The anisotropy of thermal expansion, which only displays quantum critical behavior along a-axis and not along the c-axis, indicates that geometrical frustration drives quantum criticality in this system.. Our recent study of CeRh1-xPdxSn series reveals magnetic transitions for x ≥ 0.4. The spin-flop behaviour in the magnetization curve supports the AFM ordered state. We have found that the NFL state of CeRhSn is easily transformed to an AFM ordered state with Pd doping. Our aim is to investigate complex magnetic structure and role of frustration by means of neutron diffraction study which is very important to develop new theoretical model for geometrical frustration induced quantum phase transitions.
