Fluctuations and correlations in a frustrated S=1/2 square lattice with competing ferromagnetic and antiferromagnetic interactions: a muSR study

P. Carretta, M. Filibian, R. Nath +2

Zero and longitudinal field $\mu$SR measurements in Pb${}_2$VO(PO${}_4$)${}_2$ and BaCdVO(PO${}_4$)${}_2$, two prototypes of the frustrated $S=1/2$ square lattice model with competing ferromag…
