Abstract: Microwave giant magnetoresistance in [CoFe/Cu] n nanostructures is studied in the millimeter-wave range. Measurements are preformed for superlattices with the maximum magnetoresistive effect. The field dependences of transmission and reflection coefficients are determined. Record-high (up to 80%) variations of the transmission coefficient are obtained. © 2019, Pleiades Publishing, Ltd. Acknowledgments. This study was conducted as part of the project “Spin” no.
