Abstract

We have performed a heat capacity (C_p) measurement using a relaxation method on a single-crystal sample of the S = 1 quasi-one-dimensional Heisenberg antiferromagnet Ni(C₅H₁₄N₂)₂N₃(ClO ₄) in high magnetic fields and at low temperatures. An anomaly in C_p has been observed at about 0.9 K and at 12 T. We interpret this anomaly as an indication of field induced long-range magnetic ordering. Q 1998 Elsevier Science B.V.
