The manganese doped calcium molybdato-tungstates with the formula of Ca 1- x Mn x (MoO 4 ) 0.50 (WO 4 ) 0.50 ( x = 0.01, 0.03, 0.05, 0.10, 0.125, and 0.15) were successfully obtained by two-step synthesis using in both steps a solid state reaction route. All ceramics show scheelite-type tetragonal structure with space group I4 1 /a . The electrical and magnetic studies within the temperature range of 2–300 K showed a weak p -type electrical conductivity and the paramagnetic state of Mn-doped ceramic materials. With increasing Mn content in samples under study, a change in the short-range interactions from ferromagnetic to antiferromagnetic as well as an increase in the orbital contribution to the magnetic moment, resulting in a strong spin-orbit coupling, were observed. The Brillouin procedure was used to estimate the Lande factor.

锰掺杂的钼钨酸钙中的自旋轨道耦合

通过两步法成功获得了分子式为Ca 1- x Mn x (MoO 4 ) 0.50 (WO 4 ) 0.50 ( x = 0.01、0.03、0.05、0.10、0.125和0.15)的锰掺杂钼钨酸钙在两个步骤中都使用固态反应路线合成。所有陶瓷均显示出空间群为I4 1 /a 的白钨型四方结构。在 2-300 K 温度范围内的电学和磁学研究表明，掺杂 Mn 的陶瓷材料具有弱 p 型导电性和顺磁性状态。随着所研究样品中 Mn 含量的增加，观察到从铁磁到反铁磁的短程相互作用的变化以及对磁矩的轨道贡献的增加，导致强烈的自旋轨道耦合。布里渊过程用于估计朗德因子。
