Y3+ doping increased the unit cell volume from 130.928 \u00c53 for x = 0 to 131.147 \u00c53 for x = 0.0200, and the average grain size decreased from 3.38 \u03bcm for x = 0 to 4.27 \u03bcm for x = 0.0200. The Cr and Y elements maintained +3 valence, while the Cu element had +1 valence. All samples showed obvious paramagnetism when the temperature was higher than 140 K. When the temperature continued to decrease, the lattice expansion changed the bond length and bond angle of the Cr-O-Cr bond, resulting in a change in the superexchange interaction, and the magnetic susceptibility increased significantly, gradually showing antiferromagnetism. The TN of the undoped sample was about 46 K, the TN of the doped sample with x = 0.0175 was about 21 K, and the TN of other doped samples was about 30 K. This result indicates that Y3+ doping enhanced the antiferromagnetism of the sample but also weakened its antiferromagnetic stability.<\/jats:p>","DOI":"10.3390\/ma18081827","type":"journal-article","created":{"date-parts":[[2025,4,16]],"date-time":"2025-04-16T08:09:17Z","timestamp":1744790957000},"page":"1827","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Effect of Y3+ Doping on Microstructure and Magnetic Transition of CuCrO2 Ceramics"],"prefix":"10.3390","volume":"18","author":[{"given":"Haibo","family":"Lin","sequence":"first","affiliation":[{"name":"School of Physical Science and Technology, Guangxi University, 100 East Daxue Road, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shanshan","family":"Ye","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Guangxi University, 100 East Daxue Road, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guozhu","family":"Xiong","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Guangxi University, 100 East Daxue Road, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kailai","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Guangxi University, 100 East Daxue Road, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yijing","family":"Su","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Guangxi University, 100 East Daxue Road, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kan","family":"Lu","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Guangxi University, 100 East Daxue Road, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wen","family":"Deng","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Guangxi University, 100 East Daxue Road, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1444-2534","authenticated-orcid":false,"given":"Shoulei","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Guangxi University, 100 East Daxue Road, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Dingkang","family":"Xiong","sequence":"additional","affiliation":[{"name":"School of Physical Science and Technology, Guangxi University, 100 East Daxue Road, Nanning 530004, China"},{"name":"State Key Laboratory of Featured Metal Materials and Life-Cycle Safety for Composite Structures, Nanning 530004, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,4,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"759","DOI":"10.1038\/nature05023","article-title":"Multiferroic and magnetoelectric materials","volume":"442","author":"Eerenstein","year":"2006","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"2900","DOI":"10.1002\/adma.200904326","article-title":"Magnetoelectric coupling effects in multiferroic complex oxide composite structures","volume":"22","author":"Vaz","year":"2010","journal-title":"Adv.
