Investigations of the g factors and local structure for orthorhombic Cu²+(1) site in fresh PrBa₂Cu₃O₆+x powders
The electron paramagnetic resonance (EPR) g factors gx, gy and gz of the orthorhombic Cu²⁺ (1) site in fresh PrBa₂Cu₃O₆+x powders are theoretically investigated using the perturbation formulas of the g factors for a 3d⁹ ion under orthorhombically elongated octahedra. The local orthorhombic distortio...

The electron paramagnetic resonance (EPR) g factors gx, gy and gz of the orthorhombic Cu²⁺ (1) site in fresh PrBa₂Cu₃O₆+x powders are theoretically investigated using the perturbation formulas of the g factors for a 3d⁹ ion under orthorhombically elongated octahedra.

Локальна орторомбiчна дисторцiя навколо вузла Cu²⁺(1), спричинена ефектом Яна-Теллера, описується за допомогою параметрiв ор-торомбiчного поля iз суперпозицiйної моделi.
