Abstract : Observations of the ESR signal of QnTCNQ2, a random exchange Heisenberg antiferromagnetic chain material, are reported and interpreted down to T ≤ 2.5 mK. The observed characteristics suggest that this material may be a useful thermometer and coolant via adiabatic demagnetization down to T ≤ 1 mK.
