Unexpectedly wide reversible vortex region in $\beta$-pyrochlore RbOs${}_2$O${}_6$

Pierre Legendre, Yanina Fasano, Ivan Maggio-Aprile +4

We study the extent of the reversible region in the vortex phase diagram of recently available RbOs${}_2$O${}_6$ single crystals \cite{Rogacki08a} by means of bulk magnetization measur…
