Dimensionality-driven spin-flop transition in quasi-one-dimensional PrBa2Cu4O8

Xiaofeng Xu, A. Carrington, A. I. Coldea +4

In the quasi-one-dimensional cuprate PrBa${}_2$Cu${}_4$O${}_8$, the Pr cations order antiferromagnetically at 17 K in zero field. Through a combination of magnetic susceptibility, torque…
