文摘
- •
Structural, magnetic and magnetocaloric properties of La0.7Sr0.3Mn1-xNixO3 have been investigated.
- •
Ni2+ doping results in structural transformation.
- •
The magnetic properties are suppressed with Ni2+ addition.
- •
x = 0.075 composite shows the highest RCP value of 105 J/kg.
- •
In thermoelectric measurements, Ni2+ doping decreases hole conduction.
