Abstract
We have investigated the magnetic properties of transition metal oxide superlattices with broken inversion symmetry composed of three different antiferromagnetic insulators, [NdMnO3/SrMnO3/LaMnO3]. In the superlattices studied here, we identify the emergence of a relaxor, glassy-like behavior below spin glass temperature, T=36K. Our results offer the possibility to study and utilize magnetically metastable devices confined in nano-scale interfaces.
