AC Susceptibility and Electron Spin Resonance Studies of Spin Dynamics in n Ba${}_3$NbFe${}_3$Si${}_2$O${}_{14}$: A Geometrically Frustrated Lattice

K. -Y. Choi, Z. -X. Wang, A. Ozarowski +4

We report ac susceptibility and high-frequency electron spin resonance (ESR) measurements on the geometrically frustrated compound Ba${}_3$NbFe${}_3$Si${}_2$O${}_{14}$ with the Néel temper…
