对新合成的硝酸氢氧化钴Co（OH）（NO3）-H2O体系的磁化率和磁化强度的测量表明，该体系在2.5K以上呈现低维磁行为。用具有两个最近邻交换作用的Ising型S=1/2双链来描述，J1 = 22.8K，J2 =-9.75K。钴（II）离子之间的耦合进行了讨论，使用链内和链间交换途径的结构数据
Magnetic susceptibility and magnetization measurements of the newly synthesized cobalt(II) hydroxide nitrate Co(OH)(NO 3 )-H 2 O show that this system presents above 2.5 K a low-dimensional magnetic behavior. It is described in terms of Ising-like S=1/2 double chains with two nearest-neighbor exchange interactions, J 1 =22.8 K and J 2 =-9.75 K. The couplings between cobalt(II) ions are discussed using structural data for the in-chain and interchain exchange pathways
