Muoniated radical formation and spin dynamics in molecular magnetic materials with oxalate ligands
The crystal structure of Na 2T 2(ox) 2(H 2O) 2 with T = Ni ( II ) , Co ( II ) , Fe ( II ) , and Mn(II) consists of isostructural compounds with an anionic transition metal oxalate network with a 2-leg ladder topology. We performed zero external field μ SR , longitudinal-field quenching (LFQ) and avo...
