Automation of measurements permeability of materials

The results of creating a hardware-software complex based on a precision LCR Agilent E4980A meter and a measuring cell 16454A using the LabVIEW programming environment for automated measurements of the frequency dependences of materials permeability are presented. Spectra of the real and imaginary parts of the magnetic permeability of ferrimagnets were obtained in the frequency range from 2 kHz to 2 MHz. A comparison of the measurement results with known data is performed

Determination of the anisotropy fields of polycrystalline hexaferrites by FMR

We propose the method for calculating the ferromagnetic resonance curves of polycrystalline hexaferrites with anisotropy of the easy magnetization plane.
