Abstract :
We have designed and fabricated a coplanar waveguide ferromagnetic parametric amplifier based on ferromagnetic alloy cobalt-iron (CoFe) thin film. The ferromagnetic parametric amplifier has the gain of 4 dB at 1.15 GHz. To our knowledge, it is the first coplanar waveguide ferromagnetic parametric amplifier operating at radio frequency reported to date, and we haven\´t found an item from Google search by keying in words "coplanar \´ferromagnetic parametric amplifier\´" or "coplanar \´magnetic parametric amplifier".
