## Abstract

We prospect magneto-dielectricity in $La\_{0.53}Ca\_{0.47}MnO\_{3}$ across its paramagnetic (PMI) to ferromagnetic (FMM) isostructural transition at $T\_{C} \\sim 253K$, by magnetic ($(M)$), caloric ($(W)$), dielectric ($(\\epsilon')$), magneto-resistive (MR), and magneto-capacitance (MC) investigations. Skew-broadened first-order transition character is confirmed via heating/cooling hystereses in $(M)(T)$ and $(W)(T)$, with superheating temperature $T\*\*$ almost next to $T\_C$ and supercooling temperature $T\*$ exhibiting kinetics. Above $T\_C$, linearly-related MC and MR reflect purely magneto-resistance effect. Near $T\_C$, the high-frequency MC(5T) much exceeds the magneto-losses, and is uncorrelated with dc MR(5T) in the FM-ordered state. The intrinsic magneto-dielectricity manifest below $T\_C$ and above ~kHz is traced to an intra-granular Maxwell-Wagner-type effect at the interface-region of PMI-FMM phase-coexistence.

## Recorded benchmark results

A research result applies to its stated dataset, split, metric and evaluation configuration. Compare like-for-like settings, preserve the metric's unit and direction, and distinguish paper-reported results from independent reproduction. The best result recorded here is not a claim of exhaustive, current global coverage.
