YIG Film for Magnetic Field Sensor
Acta Physica Polonica A, 2015 Single crystal Y3Fe5O12 (YIG) lm was grown onto (111) oriented gadolinium gallium garnet (GGG) substrate by the liquid phase epitaxy (PLD) technique. The X-ray di raction measurements showed that epitaxial growth of the lm along its (111) axis. The surface characteristic was investigated by atomic force microscopy (AFM) measurement.

A Low-Frequency Magnetic Field Sensor Based on Fiber Bragg Gratings
Photonics, 2022 A new type of low-frequency magnetic-field sensor based on fiber Bragg gratings (FBGs) was experimentally demonstrated for measuring the DC to low-frequency magnetic field. The operating mechanism of this AC magnetic sensor is based on the strain exerted

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Off-diagonal impedance in amorphous wires and application to linear magnetic sensors
, 2004 The magnetic-field behaviour of the off-diagonal impedance in Co-based amorphous wires is investigated under the condition of sinusoidal (50 MHz) and pulsed (5 ns rising time) current excitations. For comparison, the field characteristics of the diagonal
