The crystal field splitting
WebNov 30, 2024 · Estimate the wavelength of maximum absorption, and also the crystal field splitting $Δ_0$. I got 1.59ev for the CFS, but I want to verify if I'm doing this right. I wasn't sure if I also need to know the wavelengths of light and spin pairing energy for this problem. So I just looked up the average wavelength of red light (650nm) and plugged it ... WebNov 19, 2024 · The crystal field Hamiltonian is determined through simultaneous refinements of the inelastic neutron scattering and magnetization data. The ground-state doublet is well isolated from the other crystal field levels and results in an effective spin-1/2 system with local easy plane anisotropy at low temperature.
