Giant magnetic-field changes in radio-frequency absorption in La$_{0.67}$Sr$_{0.33}$MnO$_3$ near the Curie temperature

, 2004
The DC transport properties of and the radio-frequency (RF) wave absorption (at 2.525 MHz) in a sample of La$_{0.67}$Sr$_{0.33}$MnO$_{3}$ prepared by floating-zone method are measured. The Curie temperature, $T_{c}$, of the sample is about 374 K.

Low‐Noise, Unbiased Ferromagnetic‐Resonance‐Driven Thin‐Film Integrated Giant Magnetoimpedance Sensors

Advanced Materials Technologies, Volume 10, Issue 14, July 22, 2025.
Utilizing a novel (Ni81Fe19/Ti)4/Cu/(Ni81Fe19/Ti)4 thin‐film multilayer with low coercive field, low damping and a superior GMI ratio, a compact, low‐noise unbiased FMR‐driven integrated GMI sensor with a superior magnetic noise performance of ≈100 pT/√Hz is first demonstrated, owing to reduced phase noise from well‐defined aligned magnetic domains and

Magnetoimpedance Effect In High Permeability NiFeMo Permalloy Wires [PDF]

7th Joint MMM-Intermag Conference. Abstracts (Cat. No.98CH36275), 1998
The giant magneto-impedance effect ~GMI! has been measured in commercial HyMu80® permalloy wires, submitted to different treatments ~annealing and cold-drawing!. Although hysteresis measurements show quasibistable magnetic behavior, GMI variations as high as 160% can be found in the frequency range 1–10 MHz.

A Feedback Method to Improve the Dynamic Range and the Linearity of Magnetoimpedance Magnetic Sensor

Journal of Sensors, Volume 2019, Issue 1, 2019., 2019
We developed a high‐sensitivity magnetoimpedance magnetic field sensor using a FeCoSiB amorphous wire and a coil wound around it. The amorphous wire had the diameter of 0.1 mm and the length of 5 mm. The magnetic field resolution of about 20 pT/√Hz was achieved.
