Low Temperature Study of the Cluster Glass Phase in Ni(TCNQ)2

DOI

Recently there has been an M(TCNQ)2, where M=Mn, Co, Fe and Ni, series synthesised where all samples formed a stochiometric glassy ferromagnetic salt. We have focused on the Ni(TCNQ)2 sample where we have synthesised the deuterated form, Ni(TCNQ-D4)2, and previously performed muon spin relaxation experiments. In ZF, the relaxation could be modeled by a summation of two exponentials, which corresponds to two stopping sites. One relaxation parameter was T independent and the other showed a T dependence where as well as the Tc at 20K a low temperature (6K) divergence occurred. The 6K feature was attributed to a cluster glass phase where there is interaction of ferromagnetic clusters. We propose to further study the low temperature feature to provide more on both the static and dynamic magnetism associated with this phase.
