- •
A transition mode of PM/FM skipping AFM phase is obtained.
- •
The giant magnetocaloric effects in EuTiO3 nanowires are revealed.
- •
The magnetocaloric effects can be more remarkable in nanowires with smaller radius and larger surface tension.
- •
The magnitude of ΔT can be enhanced obviously by increasing the change of applied electric fields.
