摘要：
We report the magnetic and magnetodielectric behavior of La2CoMnO6 nanoparticles. Magnetization measurements showed two ferromagnetic (FM) transitions indicating order and disorder transitions similar to that of bulk. Dielectric behavior showed two relaxations close to the magnetic transitions. The magnetodielectric response showed MD (%) proportional to M-2 in the vicinity of paramagnetic to FM transition and MD (%) proportional to M-4 within the FM regime between 200-100 K.
