Abstract :
This article discusses the emergence of interfacial ferromagnetism in a superlattice composed of CaMnO3 antiferromagnetic insulator and CaRuO3 paramagnetic metal. Polarized neutron reflectometry is used to measure magnetization and magnetic moment of the superlattice. Results show that the emergence of interfacial ferromagnetism is highly sensitive to applied electric fields and structural distortions.
