Off-diagonal magnetoimpedance in field-annealed Co-based amorphous ribbons
, 2005 The off-diagonal magnetoimpedance in field-annealed CoFeSiB amorphous ribbons was measured in the low-frequency range using a pick-up coil wound around the sample. The asymmetric two-peak behavior of the field dependence of the off-diagonal impedance was

Advances in Condensed Matter Physics, Volume 2019, Issue 1, 2019., 2019 After one of the B atoms in Fe73.5Cu1Nb3Si13.5B9 alloy was replaced by both 0.7 Si and 0.3 Co, Fe73.5Co0.3Cu1Nb3Si14.2B8 alloy ribbons were prepared by single roll fast quenching method. The obtained alloy ribbons were subsequently wound into ring magnetic cores, and then these magnetic cores were annealed at different temperatures in air.

Operation Regimes and Design Principles of Delta‐E Effect Sensors
Advanced Sensor Research, Volume 5, Issue 4, April 2026.Delta‐E effect magnetoelectric sensors enable the detection of weak magnetic fields, yet performance optimization remains nontrivial due to coupled magnetic, mechanical, and electronic losses. A systematic study of 24 miniaturized MEMS devices with different geometries reveals three excitation‐dependent regimes: electronic‐noise, magnetic‐noise, and ...

Journal of Sensors, Volume 2017, Issue 1, 2017., 2017 Giant magnetoimpedance (GMI) has been proposed as a powerful technique for biosensing. In GMI biosensors based on the magnetic label detection the change of the impedance of sensitive element under the application of an external magnetic field was analyzed in the presence of magnetic nanoparticles in a test solution.

Advances in Magnetic Field Sensors [PDF]
, 2010 The most important milestone in the field of magnetic sensors was when AMR sensors started to replace Hall sensors in many applications where the greater sensitivity of AMRs was an advantage. GMR and SDT sensors finally found applications. We also review

Journal of Sensors, Volume 2016, Issue 1, 2016., 2016 Co68.25Fe4.5Si12.25B15 amorphous microwires with a diameter of 34 μm were prepared via the melt extraction method. The dependency of AC driving current Iac and frequency on giant magnetoimpedance (GMI) effect and magnetization were investigated using a 4294A impedance analyzer and the transverse Kerr effect. The GMI effect was analyzed when Iac changed
