In particular, monolithic bridge microfabrication has been demonstrated through the double deposition of MTJ stacks engineered by asymmetric reference layers with non-evenly layered synthetic antiferromagnet (SAF) structures. However, extending the standard double magnetic layered SAF into a triple magnetic multilayer system brings critical changes in the overall performance of the reference structure, which directly influences the magnetic stability of the device. Consequently, a theoretical model of a triple magnetic layered AF\/SAF structure was developed to support the understanding of the magnetic response of the reference layers, aiming to improve the magnetic stability around zero field. A full MTJ Wheatstone bridge incorporating the optimized double and triple reference structures was microfabricated with a linear and hysteresis-free response. Furthermore, a high thermal endurance of both structures was verified through the measurement of the magnetotransport behavior of each type of MTJ structure within a reversible magnetic field range of \u00b12\u2009kOe and a temperature sweep from room temperature up to 200\u2009\u00b0C.<\/jats:p>","DOI":"10.1063\/5.0035048","type":"journal-article","created":{"date-parts":[[2021,2,16]],"date-time":"2021-02-16T10:52:11Z","timestamp":1613472731000},"update-policy":"https:\/\/doi.org\/10.1063\/aip-crossmark-policy-page","source":"Crossref","is-referenced-by-count":13,"title":["Optimization of asymmetric reference structures through non-evenly layered synthetic antiferromagnet for full bridge magnetic sensors based on CoFeB\/MgO\/CoFeB"],"prefix":"10.1063","volume":"118","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-7339-5275","authenticated-orcid":false,"given":"Fernando","family":"Franco","sequence":"first","affiliation":[{"name":"Instituto de Engenharia de Sistemas e Computadores\u2013Microsistemas e Nanotecnologias (INESC MN) 1 , Lisbon 1000-029, Portugal"},{"name":"Instituto Superior Tecnico (IST), Universidade de Lisboa 2 , Lisbon 1049-001, Portugal"}]},{"given":"Marilia","family":"Silva","sequence":"additional","affiliation":[{"name":"Instituto de Engenharia de Sistemas e Computadores\u2013Microsistemas e Nanotecnologias (INESC MN) 1 , Lisbon 1000-029, Portugal"},{"name":"Instituto Superior Tecnico (IST), Universidade de Lisboa 2 , Lisbon 1049-001, Portugal"}]},{"given":"Susana","family":"Cardoso","sequence":"additional","affiliation":[{"name":"Instituto de Engenharia de Sistemas e Computadores\u2013Microsistemas e Nanotecnologias (INESC MN) 1 , Lisbon 1000-029, Portugal"},{"name":"Instituto Superior Tecnico (IST), Universidade de Lisboa 2 , Lisbon 1049-001, Portugal"}]},{"given":"Paulo P.","family":"Freitas","sequence":"additional","affiliation":[{"name":"Instituto de Engenharia de Sistemas e Computadores\u2013Microsistemas e Nanotecnologias (INESC MN) 1 , Lisbon 1000-029, Portugal"}]}],"member":"317","published-online":{"date-parts":[[2021,2,16]]},"reference":[{"key":"2023061717371728500_c1","doi-asserted-by":"publisher","first-page":"1","DOI":"10.1109\/TMAG.2019.2896036","article-title":"Magnetoresistive sensor development roadmap (non-recording applications)","volume":"55","year":"2019","journal-title":"IEEE Trans.
