Singularities in the AC energy losses in hard magnetic materials
No full textThe imaginary part of the reversible susceptibility
and its harmonics are measured on hard magnetic materials by the
modulation technique in a dc bias field. A singular point is observed
in the second harmonic at the anisotropy field. An interpretation
is given based on Singular Point Detection approach
Sensitive loop tracer for measuring the dynamical response of thin films in a wide audio- frequency range
No full textWe have implemented and tested a sensitive AC loop tracer, based on the principle of electro-magnetic induction, which can operate in the frequency range from 10 Hz to 10 kHz. We have studied the dynamic coercivity and loop area of thin exchange-coupled Fe/Co multilayers as a function of the magnetic field sweep-rate

Influence of domain walls on the singular point detection of energy losses in hard magnetic materials
No full textThe imaginary part of the second harmonic of the reversible parallel susceptibility (RPS) has been recently demonstrated to be a sensitive probe for determining the anisotropy fields in polycrystalline hard magnetic materials, by means of the singular point detection technique (SPD). A modified SPD theory is depicted here considering the presence of domain walls in the multi-domain crystallites, on the basis of Néel's phase theory. Measurements performed on Ba-ferrite random powder show that the energy losses related to domain wall motion are likely at the origin of the observed effect
