- ●
Charge-ordered state appears for the Co3O4 nanoplatelets but absent for the nanorings.
- ●
Quite significant exchange bias is only observed for Co3O4 nanorings.
- ●
Exchange bias behavior of Co3O4 nanorings is consistent with spin-glass like shell.
- ●
Potential for ultrahigh-density magnetic recording and spin valve devices.
