- Abstract:
-
We present an investigation of magnetic ordering in the two-dimensional S=1/2 quantum magnet Cu(Pz)2(ClO4)2 using specific heat and zero-field muon-spin relaxation (μ+SR). The magnetic contribution to the specific heat is consistent with an exchange strength of 17.7(3) K. We find unambiguous evidence for a transition to a state of three-dimensional long-range order below a critical temperature TN=4.21(1) K using μ+SR even though there is no feature in the specific heat at that temperature.
