It was found that the maximum MI value exceeds 200%, which may be of interest in the development of magnetic field sensors. It is also shown that practically significant characteristics of the MI response strongly depend on the ac frequency, which is due to the inhomogeneous distribution of magnetic properties over the ribbon cross section. This distribution was studied using magnetoimpedance tomography based on the analysis of the experimental dependences of the reduced impedance on the ac frequency.<\/jats:p>","DOI":"10.3390\/s23198283","type":"journal-article","created":{"date-parts":[[2023,10,9]],"date-time":"2023-10-09T06:16:48Z","timestamp":1696832208000},"page":"8283","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Magnetoimpedance Effect in Cobalt-Based Amorphous Ribbons with an Inhomogeneous Magnetic Structure"],"prefix":"10.3390","volume":"23","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8486-1849","authenticated-orcid":false,"given":"Dmitry A.","family":"Bukreev","sequence":"first","affiliation":[{"name":"Department of Physics, Pedagogical Institute, Irkutsk State University, 664003 Irkutsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0074-0335","authenticated-orcid":false,"given":"Michael S.","family":"Derevyanko","sequence":"additional","affiliation":[{"name":"Department of Physics, Pedagogical Institute, Irkutsk State University, 664003 Irkutsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alexander V.","family":"Semirov","sequence":"additional","affiliation":[{"name":"Department of Physics, Pedagogical Institute, Irkutsk State University, 664003 Irkutsk, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2023,10,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6209","DOI":"10.1063\/1.358313","article-title":"Sensitive field- and frequency-dependent impedance spectra of amorphous FeCoSiB wire and ribbon (invited)","volume":"76","author":"Beach","year":"1994","journal-title":"J.
