On the power spectrum of magnetization noise [PDF]
, 2001 Understanding the power spectrum of the magnetization noise is a long standing problem. While earlier work considered superposition of 'elementary' jumps, without reference to the underlying physics, recent approaches relate the properties of the noise ...

Standalone Integrated Magnonic Devices
Advanced Materials, Volume 37, Issue 40, October 9, 2025.A standalone (not requiring external bias magnetic field) and tunable magnonic device is reported with all‐electric input and output, fully integrated on silicon (total footprint of 100 × 150 µm) and 3–8 GHz frequency band. This is achieved by monolithic integration of a CoFeB conduit with RF antennas and an assembly of NiFe and SmCo micromagnets ...

Signature of effective mass in crackling noise asymmetry
, 2005 Crackling noise is a common feature in many dynamic systems [1-9], the most familiar instance of which is the sound made by a sheet of paper when crumpled into a ball.

Advanced Materials Technologies, Volume 10, Issue 18, September 18, 2025.A theoretical framework links stress‐induced changes in the Young's modulus of Fe₇₂Ga₂₈ layers to their magnetization dynamics under SH‐SAW excitation. This interaction produces a sharp sensor response near the coercive field, highlighting FeGa's magnetoelastic sensitivity.

Research on the Orthogonal Fundamental Mode Fluxgate Sensor Circuit
IEEE Access, 2020 Currently, magnetic fluxgate circuits used for magnetic field measurements mostly adopt parallel excitation second harmonic generation. The magnetic fluxgate developed by this method cannot possess both low noise and high bandwidth at the same time.
