文摘
- •
I-V characteristics study of NiFe2O4 nanoparticles with varying particle sizes.
- •
Experiments evident electrical hysteretic behaviour, i.e., electrical memory effect.
- •
Magnetic field dependent electrical irreversibility is due to magnetostriction.
- •
A phenomenological model has been proposed on the light of induced polarization.
- •
Such electrical irreversibility decreases with increasing particle sizes.
