Paramagnetic Complexes in Zinc Selenide Crystals with Iron Admixture

Аннотация

Paramagnetic resonance of ZnSe: Fe single crystals was studied at 120 K. Parameters of the spin Hamiltonian were determined for the monoclinic dimer complex Fe³⁺–Cu⁺ and a second discovered Fe³⁺ center, which appears due to association of the iron ion with a K⁺ ion in a Zn²⁺ position or with a zinc vacancy. Effect of illumination of the zinc selenide samples by blue, green and red light on the paramagnetic resonance spectrum was investigated.
