At present, the method to suppress the influence of low frequency noise is mainly to modulate the measured magnetic field by mechanical resonance. In this paper, a novel modulation concept employing a magnetoelectric coupling effect is proposed. A design method of modulation structure based on an equivalent magnetic circuit model (EMCM) and a single domain model of in-plane moment was established. An EMCM was established to examine the relationship between the permeability of flux modulation film (FMF) and modulation efficiency, which was further verified through a finite element simulation model (FESM). Then, the permeability modulated by the voltage of a ferroelectric\/ferromagnetic (FE\/FM) multiferroic heterostructure was theoretically studied. Combining these studies, the modulation structure and the material were further optimized, and a FeSiBPC\/PMN-PT sample was prepared. Experimental results show that the actual magnetic susceptibility modulation ability of FeSiBPC\/PMN-PT reached 150 times, and is in good agreement with the theoretical prediction. A theoretical modulation efficiency higher than 73% driven by a voltage of 10 V in FeSiBPC\/PMN-PT can be obtained. These studies show a new concept for magnetoelectric coupling application, and establish a new method for magnetic field modulation with a multiferroic heterostructure.<\/jats:p>","DOI":"10.3390\/s20051440","type":"journal-article","created":{"date-parts":[[2020,3,6]],"date-time":"2020-03-06T09:26:41Z","timestamp":1583486801000},"page":"1440","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Novel Magnetic Field Modulation Concept Using Multiferroic Heterostructure for Magnetoresistive Sensors"],"prefix":"10.3390","volume":"20","author":[{"given":"Long","family":"Pan","sequence":"first","affiliation":[{"name":"College of Intelligence Science and Technology, National University of Defense Technology, Changsha 410073, Hunan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mengchun","family":"Pan","sequence":"additional","affiliation":[{"name":"College of Intelligence Science and Technology, National University of Defense Technology, Changsha 410073, Hunan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jiafei","family":"Hu","sequence":"additional","affiliation":[{"name":"College of Intelligence Science and Technology, National University of Defense Technology, Changsha 410073, Hunan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4670-5615","authenticated-orcid":false,"given":"Yueguo","family":"Hu","sequence":"additional","affiliation":[{"name":"College of Intelligence Science and Technology, National University of Defense Technology, Changsha 410073, Hunan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yulu","family":"Che","sequence":"additional","affiliation":[{"name":"College of Intelligence Science and Technology, National University of Defense Technology, Changsha 410073, Hunan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yang","family":"Yu","sequence":"additional","affiliation":[{"name":"College of Intelligence Science and Technology, National University of Defense Technology, Changsha 410073, Hunan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Nan","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Zhejiang University, Hangzhou 310027, Zhejiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weicheng","family":"Qiu","sequence":"additional","affiliation":[{"name":"College of Intelligence Science and Technology, National University of Defense Technology, Changsha 410073, Hunan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peisen","family":"Li","sequence":"additional","affiliation":[{"name":"College of Intelligence Science and Technology, National University of Defense Technology, Changsha 410073, Hunan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Junping","family":"Peng","sequence":"additional","affiliation":[{"name":"College of Intelligence Science and Technology, National University of Defense Technology, Changsha 410073, Hunan, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jianzhong","family":"Jiang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Zhejiang University, Hangzhou 310027, Zhejiang, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,6]]},"reference":[{"key":"ref_1","first-page":"1","article-title":"Designs of novel magnetic flux guides for three-Axis magnetic sensor","volume":"51","author":"Zhao","year":"2015","journal-title":"IEEE Trans.
