Abstract

Paramagnetic centers formed by isotopically pure ⁵³Cr impurity ions in synthetic forsterite (Mg₂SiO₄) were studied by continuous wave electron paramagnetic resonance spectroscopy. The chromium ions were shown to replace magnesium ions in the M1 and M2 crystallographic sites of the forsterite crystal lattice in the form of single Cr³⁺ and Cr²⁺ ions and as a dimer associate formed by two closely spaced Cr³⁺ ions connected by an exchange interaction. The parameters of the hyperfine interaction between the electron and nuclear spins were determined for single ions.

合成Forsterite Mg2SiO4中53Cr杂质离子EPR谱的超精细结构

用连续波电子顺磁共振波谱法研究了合成forsterite （Mg2SiO4）中同位素纯53Cr杂质离子形成的顺磁中心。铬离子以单个Cr3+和Cr2+离子的形式取代镁离子，并以交换相互作用连接的两个紧密间隔的Cr3+离子形成二聚体缔合物。测定了单离子中电子与核自旋之间超精细相互作用的参数。
