项目摘要
Anomalous magnetic behaviors of honeycomb lattice compound Na_3M_2SbO_6 and Na_2M_2TeO_6 (M=Cu, Ni and Co) have been investigated by means of neutron scattering and measurements of magnetic susceptibility x and specific heat C. For M=Cu, spin-gap behaviors have been observed in the temperature dependences of x and C. In order to extract information of an origin of the spin-gap, magnetic excitation spectra have been measured by neutron inelastic scattering on a single crystal of Na_3Cu_2SbO_6. From the intensity distribution and the dispersion curves of the excitations, we have evaluated the values of spin-gap and exchange interactions. The results of x and C data of Na_3Ni_2SbO_6, Na_3Co_2SbO_6, Na_2Ni_2TeO_6, and Na_2Co_2TeO_6 indicate that the spin systems exhibit an antiferromagnetic transition at TN=18K, 6K, 34K, and 25K, respectively. To investigate the magnetic structure of these systems, neutron diffraction studies have been carried out for the polycrystalline samples. We can determine the magnetic structure of Na_3Ni_2SbO_6, and Na_2Co_2TeO_6.
通过中子散射和磁化率x和比热C的测量,研究了蜂窝晶格化合物Na_3M_2SbO_6和Na_2M_2TeO_6(M=Cu、Ni和Co)的反常磁行为。对于M=Cu,在x和C的温度依赖性中观察到自旋间隙行为。为了提取自旋间隙起源的信息,磁激发光谱 通过 Na_3Cu_2SbO_6 单晶上的中子非弹性散射进行了测量。根据激发的强度分布和色散曲线,我们评估了自旋间隙和交换相互作用的值。 Na_3Ni_2SbO_6、Na_3Co_2SbO_6、Na_2Ni_2TeO_6和Na_2Co_2TeO_6的x和C数据结果表明,自旋体系分别在TN=18K、6K、34K和25K时表现出反铁磁转变。为了研究这些系统的磁结构,对多晶样品进行了中子衍射研究。我们可以确定Na_3Ni_2SbO_6和Na_2Co_2TeO_6的磁性结构。
