I am trying to excite spin-wave in a BLIG film via applying microwave current to one micro-strip line and detecting the transmission at another micro-strip line. The problem I am facing is the transmission due to electromagnetic coupling is masking the spin-wave transmission. Unfortunately, designing a new micro-strip line is not an option at this moment. How to separate the spin-wave transmission part and EM transmission part?
Does the spin wave require a bias field? If so turn it on and off and detect at that frequency.
As I am interested in generating surface spin-wave, I am applying an in-plane bias magnetic field.
Modulate the magnetic field and only detect the signal that changes at that frequency.
Malcolm White Thank you for the suggestion. I will try to do that.
As commented to similar question a moment ago:
Perhaps you have (microwave) magnetostatic wave devices in mind..there was a lot of research and many PhD thesis in this field about 40 years ago.
