Morphology-Controlled Synthesis of CeO2 Microstructures and Their Room Temperature Ferromagnetism

- Gear shape CeO2 microstructures with enhanced RTFM are synthesized via a facile hydrothermal method.
- A mechanism for enhanced RTFM of gear shape CeO2 microstructures is proposed.
- A possible formation mechanism is suggested to explain the growth of gear shape CeO2 microstructures.
- The enhanced RTFM should make the CeO2 microstructures excellent candidates for applications in related areas.
