Charge-stripe order, antiferromagnetism, and spin dynamics in the cuprate-analog nickelate La${}_4$Ni${}_3$O${}_8$

Oscar O. Bernal, Douglas E. MacLaughlin, Gerald D. Morris +7

We report a muon spin rotation ($\mu$SR) study of the cuprate-analog nickelate La${}_4$Ni${}_3$O${}_8$, which undergoes a transition at 105 K to a low-temperature phase with charge-stripe…
