Abstract
Large high energy magnetodielectric effects are observed in the bilayer manganite (La0.4Pr0.6)1.2Sr1.8Mn2O7, a direct consequence of exploiting magnetoresistance changes associated with the field driven spin-glass insulator to ferromagnetic metal transition and its high temperature remnant. The low temperature magnetodielectric contrast is as large as ∼100% near 0.8eV at 10T and over 10 000% in selected phonon regions. The 300K magnetodielectric contrast is ∼20% near 1.1eV at 30T. The results are potentially useful for magnetic memory applications away from the dc limit.
