Large exchange bias and low temperature glassy state in frustrated triangular-lattice antiferromagnet Ba${}_3$NiIr${}_2$O${}_9$

Shobha Gondh, Manju Mishra Patidar, Kranti Kumar +3

Here, we report both ac and dc magnetization, thermodynamic and electric properties of hexagonal Ba${}_3$NiIr${}_2$O${}_9$. The Ni${}^{2+}$ (spin-1) forms layered triangular-lattice and in…
