Transport and magnetic anomalies due to A-site ionic size mismatch in La${}_{0.5}$Ca${}_{0.5-x}$Ba_{x}MnO${}_3$

R. Mallik, E. S. Reddy, P. L. Paulose +2

We present results of electrical resistivity, magnetoresistance and ac and dc magnetic susceptibility on polycrystalline samples of the type La(0.5)Ca(0.5-x)Ba(x)MnO(3) synthesized…
