Frequency characteristics of the one-layer anisotropic magnetoresistive sensitive nanoelements

The high-frequency characteristics of the one-layer anisotropic magnetoresistive strip – the magnetosensitive nanoelement of the magnetic field sensor – were analyzed on the basis of the Landau–Livshits–Hilbert equation. The results of this study were shown to coincide completely with the linear microwave theory. The strip frequency characteristics were analyzed for low-anisotropy and high-anisotropy FeNiCo ferromagnetic films of various thickness, strip width, easy magnetization direction, and fixed external magnetic field.
