Multiple transient spectral holes in the R1-line of NaMgAl(oxalate)3·9H2O∶Cr(iii). Probing excited and ground state g-factors in an external magnetic field of 15 mT
Abstract
The gz-factors of the 4A2 ground state and the 2E excited state of chromium(III) doped into NaMgAl(oxalate)3·9H2O are accurately determined at 2.5 K by the observation of multiple transient spectral holes in the R1-line (2E←4A2 transition) in minute magnetic fields of ≈15 mT.
