Physical properties in the cluster-based magnetic-diluted triangular lattice antiferromagnets Li2Sc[1-x]Sn[x]Mo[3]O[8]

Abstract

We have investigated the physical properties of the magnetic diluted triangular lattice antiferromagnetic system Li2Sc[1-x]Sn[x]Mo[3]O[8]. For all compounds, no mangetic ordering has been observed. On the other hand, the partial spin disappearing behavior is found in all Sn-substituted compounds except x = 0, which has been also observed in the similar magnetic system LiZn[2]Mo[3]O[8]. Considering the relationship between the crystal structure and the magnetism, the partial spin disappearance is properly explained by a formation of the valence bond glass derived from the randomness effect
