Microwave magnetic properties of twisting structure in artificial ferrimagnet Py/Gd multilayers
Source abstract
Abstract
The noncollinear magnetic structure is attracting significant attention owing to its abundant characteristics as well as its potential applications in spintronic devices. In this work, the magnetic characteristics for an artificial ferrimagnetic Py/Gd multilayer system having the magnetic twisted state were investigated. With an increasing thickness (1.4 to 4 nm) of the Gd layer ( t Gd), the effective magnetization decreased initially until t Gd = 2.5 nm and then increased, which was found to be induced by the change of magnetic twisted state due to antiferromagnetic coupling between Py and Gd. Moreover, the effective Gilbert damping factor was found to be completely opposite to the effective magnetization with increasing t Gd . Our results provided detailed insights into the microwave magnetic properties of an artificial ferrimagnet with a noncollinear magnetic structure that provides alternative material in the application of spintronic devices
