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.

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.

A large magnetoinductance effect in La0.67Ba0.33MnO3
, 2009 We report four probe impedance of La0.67Ba0.33MnO3 at f = 100 kHz under different dc bias magnetic fields. The ac resistance (R) exhibits a peak around Tp = 325 K which is accompanied by a rapid increase and a peak in the reactance (X) in a zero field ...

Magnetoimpedance Effects in Electrodeposited NiFe Nanowire Array
Acta Physica Polonica A, 2014 In this work, NiFe nanowires were grown in highly ordered porous anodic alumina oxide templates by dc electrodeposition at a pH value of 2.6. Scanning electron microscopy showed that wires have diameters of about 250 310 nm and length 25 30 μm. The energy dispersive X-ray analysis showed that the composition of the nanowires is Ni65Fe35.

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
