Pressure-Invariant Isotope Effect as Evidence for Electronically Driven Intertwined Order in Pr${}_4$Ni${}_3$O${}_{10}$

Rustem Khasanov, Thomas J. Hicken, Igor Plokhikh +5

We report muon-spin rotation measurements of the pressure dependence of the oxygen-isotope (${}^{16}$O/${}^{18}$O) effect on the spin-density wave (SDW) transition in the trilayer Rudd…
