Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns occurs. We believe that a knowledge of the local magnetic nature of this system may shed light on the origin of magnetic order in TCNQ-related molecular ferromagnets. We therefore propose to use uSR to study the local magnetic properties of KTCNQ and related compounds to clarify the magnetic structure of TCNQ salts in general. We will use the EMU instrument to make zero field and longitudinal field measurements on materials such as KTCNQ KTCNQ-d4 and KTCNQCl2 to investigate the effect of changes molecular structure on local magnetic properties. Measurements will be made at 300K-500K, in the vicinity of the SP transition, and at low (<30K) temperatures where a Curie tail dominates the magnetic susceptibility of KTCNQ.
