Title: Partially disordered state with short-range spin correlation in $S = 5 / 2$ classical triangular antiferromagnet ${Ag}_{2} {FeO}_{2}$

Abstract

A triangular-lattice antiferromagnet of ${Ag}_{2} {FeO}_{2}$ was synthesized under high pressure. Its magnetism was studied in terms of electrical resistivity, magnetic susceptibility, heat capacity, powder neutron scattering, and Mössbauer spectroscopy. The magnetic state of ${Ag}_{2} {FeO}_{2}$ changes successively through a second-order phase transition at $T_{p} = 36$ K and a crossover at $T_{c} = 20$ K. A partially disordered (PD) state appears below $T_{p}$ , in which $\approx 2/3$ spins are ordered and the remaining $\approx 1/3$ spins fluctuate, which state persists at least down to 5 K. The spin correlation length starts to grow at $T_{p}$ ; however, it remains very short ( $\approx 27$ Å) below $T_{c}$ . This exotic magnetism is concerned with strong frustration in the classic antiferromagnetic triangular lattice.
