Effect of Joule-Heating Annealing on Giant Magnetoimpedance of Co64Fe4Ni2B19-xSi8Cr3Alx (x = 0, 1 and 2) Melt-Spun Ribbons [PDF]

Journal of Ultrafine Grained and Nanostructured Materials, 2017
In this work, we have studied the influence of dc joule-heating thermal processing on the structure, magnetoimpedance (MI) and thermal properties of Co64Fe4Ni2B19-xSi8Cr3Alx (x = 0, 1, and 2) rapidly solidified melt-spun ribbons.

Influence of length and measurement geometry on magnetoimpedance in La0.7Sr0.3MnO3

, 2009
We show that ac magnetoresistance at room temperature in La0.7Sr0.3MnO3 is extremely high (= 47% in H = 100 mT, f = 3-5 MHz), and magnetic field dependence of reactance exhibits a double peak behavior.

Modeling of asymmetric giant magnetoimpedance in amorphous ribbons with a surface crystalline layer

, 2005
A model describing the asymmetric giant magnetoimpedance (GMI) in field-annealed amorphous ribbons is proposed. It is assumed that the ribbon consists of an inner amorphous core and surface hard magnetic crystalline layers.

Phenomenological theory of the giant magnetoimpedance of composite wires

, 2012
Composite wires with a three-layered structure are known to show a particularly large magnetoimpedance effect. The wires consist of a highly conductive core, an insulating layer and an outer ferromagnetic shell.
