Magnetism of cobalt during oxidative ageing: A theory supported experimental investigation

Exchange bias mediated self-biased magnetoelectric coupling in Co–BaTiO3 composites

“…The formation kinetics of cobalt oxide at the surface of Co has been thoroughly discussed in our previous research. 18 Hence, we conclude that the observed EB is due to the coupling between Co and cobalt oxide at the Co-BTO interface.…”

“…In our recently reported work, we have studied the properties of micro-sized Co particles (CP) and Co chains (CC). 18 In the present investigation also, CP and CC samples were developed via a similar wet-chemical reduction route, as reported earlier. 18 For preparing the ME composites, fresh samples of CP and CC were taken as the ferromagnetic (FM) constituents, while BTO was the ferroelectric (FE) component.…”

The BTO sample was prepared using the same technique as described in our earlier work.…”
