Giant Nonreciprocity of Surface Acoustic Waves induced by a positive-negative magnetostrictive heterostructure
Wenbin Hu, Mingxian Huang, Yutong Wu +3
Lack of nonreciprocity is one of the major drawbacks of solid-state acoustic devices, which has hindered the development of microwave-frequency acoustic isolators and circulators.…

Large Nonreciprocity of Shear-Horizontal Surface Acoustic Waves induced by Magnetoelastic Bilayers
Mingxian Huang, Yuanyuan Liu, Wenbin Hu +5
We report large nonreciprocity in the transmission of shear-horizontal surface acoustic waves (SAWs) on LiTaO3 substrate coated with a FeCoSiB/NiFeCu magnetoelastic bilayer. The la…

Observation of Enhanced Dynamic ΔG effect near Ferromagnetic Resonance Frequency
Wenbin Hu, Yudi Wang, Mingxian Huang +2
The field-dependence elastic modulus of magnetostrictive films, also called ΔE or ΔG effect, is crucial for ultrasensitive magnetic field sensors based on surface acoustic waves (S…
