Anomalous dielectric constant of half-doped manganite La0.5Ca0.5MnO3.

Highlights: [•] ɛ′(T) of La0.5Ca0.5MnO3 are investigated by EOM GF. [•] The intensity of ɛ′(T) reduced with the increase of |ɛJT |, V, U. [•] TP rises as |ɛJT |, V, and U increase. [•] TP remains unchanged and ɛ′(T) increased with the increase of g. [•] The calculated results of ɛ′(T) are explained theoretically. [Copyright &y& Elsevier]
