Magnetoimpedance spectroscopy of phase-separated LaCaMnO polycrystalline manganites.

Magnetoimpedance spectroscopy was carried out on phase-separated LaCaMnO polycrystalline manganites. The LaCaMnO powder was synthesized following an adapted sol-gel route. Structural and magnetic data showed the signs of phase coexistence of ferromagnetic (FM) Pnma and charge-ordered antiferromagnetic (CO-AFM) P2/m phases.
