Influence of magnetic relaxation on magnetoelastic resonance-based detection
(IOP, 2023-02)
The phenomenon of magnetic relaxation in amorphous ferromagnetic alloys can result in an
undesired time evolution of the magnetization that produces serious drawbacks in the use of
these materials in sensor applications. ...
