Abstract

NiX2(pyz)2 have been synthesized and characterized using several magnetic probes. Except for X = Cl, long-range AFM order was found below TN = 1.9 (X = Br and NCS) and 2.5 K (X = I). In addition, Jpyz ∼ 1 K regardless of X, and D = 8 K for NiCl2(pyz)2, whereas D ∼ 0 for X = Br, I, and NCS based on ESR and heat capacity.
