Pressure-Induced Metallization in Iron-Based Ladder Compounds Ba${}_{1-x}$Cs${}_x$Fe${}_2$Se${}_3$

Takafumi Hawai, Chizuru Kawashima, Kenya Ohgushi +5

Electrical resistivity measurements have been performed on the iron-based ladder compounds Ba${}_{1-x}$Cs${}_x$Fe${}_2$Se${}_3$ ($x$ = 0, 0.25, 0.65, and 1) under high pressure. A cubic an…
