Which outcome arises when doping introduces mismatched d-orbitals in manganite perovskites?

A)Colossal magnetoresistance emerges✓

B)Improved chemical stability occurs

C)Superconducting transition increases

D)Dielectric breakdown strength increases

💡 Explanation

Colossal magnetoresistance appears due to double exchange, where ferromagnetic order and conductivity are maximized when electron transfer is unimpeded. This outcome happens because the spin alignment minimizes electron scattering, therefore magnetoresistance is colossal, rather than weak, under other scattering conditions.
