Article Synopsis
- P nuclear magnetic resonance (NMR) studies reveal key insights into the magnetic properties and spin dynamics of Fe spins in NaFe(PO), a two-dimensional triangular lattice compound.
- A significant peak in the nuclear spin-lattice relaxation rate (1/T1) at the Néel temperature (TN=10.9K) indicates an antiferromagnetic transition, with an estimated exchange coupling of J/kB≃1.9K.
- The findings suggest that NaFe(PO) exhibits a conventional three-dimensional antiferromagnetic state characterized by specific NMR spectral shapes and strong temperature-dependent spin wave behaviors, with no evidence of spin frustration.
