在液氮温度下，用脉冲强磁场和两种亚毫米波（337 μm HCN激光和119 μm H2O激光）研究了钴铵图顿盐（NH 4）2Co（SO 4）2 ·6 H2O的亚毫米ESR。观察到g值的频率依赖性。例如g||在119 µm处比在337 µm处小约2%。通过在有效自旋哈密顿量中引入新的SH 3项，可以解释所观察到的频率依赖性。基于Abragam-Pryce理论的广泛的理论考虑表明，所观察到的位移可以令人满意地定量解释。这是首次在离子晶体中观测到铁族离子的SH 3项。
Submillimeter ESR in cobalt ammonium Tutton salt (NH 4 ) 2 Co(SO 4 ) 2 ·6H 2 O was studied at liquid nitrogen temperature using pulsed high magnetic fields and two submillimeter waves, 337 µm of HCN laser and 119 µm of H 2 O laser. The frequency dependence of the g value was observed. For example, g || at 119 µm was about 2% smaller than that at 337 µm. The observed frequency dependence can be explained by introducing a new S H 3 term in the effective spin Hamiltonian. An extensive theoretical consideration based on the Abragam-Pryce theory shows that the observed shift can satisfactorily be explained quantitatively. This is the first experimental observation of S H 3 term of the iron group ions in ionic crystals.
