Here, we demonstrate a compact construction of a three-axis vector atomic magnetometer. The magnetometer is operated with a single laser beam and with a specially designed triangular 87Rb vapor cell (side length is 5 mm). The ability of three-axis measurement is realized by reflecting the light beam in the cell chamber under high pressure, so that the atoms before and after reflection are polarized along two different directions. It achieves a sensitivity of 40 fT\/Hz in x-axis, 20 fT\/Hz in y-axis, and 30 fT\/Hz in z-axis under spin-exchange relaxation-free regime. The crosstalk effect between different axes is proven to be little in this configuration. The sensor configuration here is expected to form further values, especially for vector biomagnetism measurement, clinical diagnosis, and field source reconstruction.<\/jats:p>","DOI":"10.3390\/s23063148","type":"journal-article","created":{"date-parts":[[2023,3,16]],"date-time":"2023-03-16T03:14:35Z","timestamp":1678936475000},"page":"3148","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":15,"title":["An Integrated Single-Beam Three-Axis High-Sensitivity Magnetometer"],"prefix":"10.3390","volume":"23","author":[{"given":"Shengran","family":"Su","sequence":"first","affiliation":[{"name":"Zhejiang Provincial Key Laboratory for Quantum Precision Measurement, College of Science, Zhejiang University of Technology, Hangzhou 310023, China"}]},{"given":"Zhenyuan","family":"Xu","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Key Laboratory for Quantum Precision Measurement, College of Science, Zhejiang University of Technology, Hangzhou 310023, China"},{"name":"Hangzhou Qmag Technology Co., Ltd., Hangzhou 310023, China"}]},{"given":"Xiang","family":"He","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Key Laboratory for Quantum Precision Measurement, College of Science, Zhejiang University of Technology, Hangzhou 310023, China"}]},{"given":"Chanling","family":"Yin","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Key Laboratory for Quantum Precision Measurement, College of Science, Zhejiang University of Technology, Hangzhou 310023, China"}]},{"given":"Miao","family":"Kong","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Key Laboratory for Quantum Precision Measurement, College of Science, Zhejiang University of Technology, Hangzhou 310023, China"}]},{"given":"Xuyuan","family":"Zhang","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Key Laboratory for Quantum Precision Measurement, College of Science, Zhejiang University of Technology, Hangzhou 310023, China"}]},{"given":"Yi","family":"Ruan","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Key Laboratory for Quantum Precision Measurement, College of Science, Zhejiang University of Technology, Hangzhou 310023, China"}]},{"given":"Kan","family":"Li","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Key Laboratory for Quantum Precision Measurement, College of Science, Zhejiang University of Technology, Hangzhou 310023, China"}]},{"given":"Qiang","family":"Lin","sequence":"additional","affiliation":[{"name":"Zhejiang Provincial Key Laboratory for Quantum Precision Measurement, College of Science, Zhejiang University of Technology, Hangzhou 310023, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,15]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"2505","DOI":"10.1103\/PhysRevLett.86.2505","article-title":"New limit on the permanent electric dipole moment of 199 Hg","volume":"86","author":"Romalis","year":"2001","journal-title":"Phys.
