Synthetic Antiferromagnetic Coupling Between Ultrathin Insulating Garnets
Synthetic Antiferromagnetic Coupling Between Ultrathin Insulating Garnets
Antiferromagnetic materials are gaining importance in spintronic applications, because of their stability against external magnetic field perturbations. This work investigates a negative exchange interaction between two insulating ferrimagnets, yttrium iron garnet and gadolinium iron garnet. The authors demonstrate that a heterostructure based on these insulating garnets behaves as a synthetic …
