Stress level in finemet materials studied by impedanciometry
(2002) [Journal article]In this work, a study of the stress relief in Finemet ribbons, Fe73.5Cu1Nb3Si16.5B6, as a function of the annealing temperature is presented. The as melt-spun samples are amorphous and become partially crystallized after ... -
Tunable asymmetric magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films
(2014) [Journal article]We investigate the magnetization dynamics through the magnetoimpedance effect in ferromagnetic NiFe/Cu/Co films. We observe that the magnetoimpedance response is dependent on the thickness of the non-magnetic Cu spacer ...
