Strain-induced ferromagnetism in antiferromagnetic LuMnO3 thin films

Abstract

Single phase and strained LuMnO3 thin films are discovered to display co-existing ferromagnetic and antiferromagnetic orders. A large moment ferromagnetism (approx. 1 muB), which is absent in bulk samples, is shown to display a magnetic moment distribution that is peaked at the highly-strained substrate-film interface. We further show that the strain-induced ferromagnetism and the antiferromagnetic order are coupled via an exchange field, therefore demonstrating strained rare-earth managanite thin films as promising candidate systems for new multifunctional devices.
