Anomalous pressure effect on the remanent lattice striction of a (La,Pr)${}_{1.2}$Sr${}_{1.8}$Mn${}_2$O${}_7$ bilayered manganite single crystal

We have studied the pressure effect on magnetostriction, both in the $ab$-plane and along the c-axis, of a (La,Pr)${}_{1.2}$Sr${}_{1.8}$Mn${}_2$O${}_7$ bilayered manganite single cryst…
