We present the results of a muon-spin relaxation (mu+SR) study of magnetic order in the quasi-one-dimensional spin-1/2 molecular chain compound Cu(HCO2)(2)(C4H4N2). Zero-field mu+SR measurements at low temperatures show oscillations in the measured asymmetry, characteristic of a quasistatic magnetic field at the muon sites. Our measurements provide convincing evidence for long-range magnetic order below a temperature T-N=1.97(8) K. This leads to an estimate of the interchain coupling constant of parallel to J'parallel to/k(B)=1.27 K and to a ratio parallel to J'/J parallel to=1.6x10(-1).

We present evidence of magnetic order in the quasi-one-dimensional spin-1/2 molecular chain compound, copper pyrazine dinitrate Cu(C4H4N2)(NO3)(2). Zero field muon-spin relaxation measurements made at dilution refrigerator temperatures show oscillations in the measured asymmetry characteristic of a quasistatic magnetic field at the muon sites. Our measurements provide convincing evidence for long-range magnetic order below a temperature T-N=107(1) mK. This leads to an estimate of the interchain coupling constant of vertical bar J'vertical bar/k(B)=0.046 K and to a ratio of vertical bar J'/J vertical bar=4.4x10(-3).
