Absence of magnetic order and emergence of unconventional fluctuations in $J_{\mathrm{eff}}=1/2$ triangular lattice antiferromagnet YbBO${}_3$

K. Somesh, S. S. Islam, S. Mohanty +6

We present the ground state properties of a new quantum antiferromagnet YbBO${}_3$ in which the isotropic Yb${}^{3+}$ triangular layers are separated by a non-magnetic layer of partial…
