Evolution of complex magnetic phases and metal-insulator transition through Nb substitution in La${}_{0.5}$Sr${}_{0.5}$Co${}_{1-x}$Nb${}_x$O${}_3$

Rishabh Shukla, R. S. Dhaka

We report the evolution of structural, magnetic, transport, and electronic properties of bulk polycrystalline La${}_{0.5}$Sr${}_{0.5}$Co${}_{1-x}$Nb${}_x$O${}_3$ ($x=$ 0.025--0.25) samples.…
