Detection of weak-order phase transitions in ferromagnets by ac resistometry

open access: yes, 2003
It is shown that ac resistometry can serve as an effective tool for the detection of phase transitions, such as spin reorientation or premartensitic phase transitions, which generally are not disclosed by dc resistivity measurement.

Giant Magnetoimpedance Effect in NiFeMo Permalloy Ribbon

open access: yesMaterials Transactions, JIM, 2000
In the present paper, the dc longitudinal field and ac frequency dependence of the magnetoimpedance, magnetoresistance, magnetoreactance and magnetoimpedance-phase of NiFeMo permalloy ribbon are investigated. The value of the magnetoimpedance ratio (Z(0) - Z(5172A.m -1 ))/Z(0) of NiFeMo permalloy ribbon can reach 39.54% at 0.3MHz.

Magnetic properties and giant magnetoimpedance effect for CoFeMoSiB surface modified amorphous ribbons covered by water based ferrofluid

open access: yesEPJ Web of Conferences, 2018
Giant magnetoimpedance (GMI) effect is a powerful technique for magnetic label detection. Co-based amorphous ribbons are cheap materials showing high GMI effect at low operation frequencies for close to zero magnitostriction compositions.
