The antiferromagnetic structure sublattice and the ferromagnetic structure sublattice had coexisted and competed with each other. Previous works are focus on studying magnetic properties of RFexMn12\u2212x (x = 0\u20139.0, \u0394x = 0.2). In this work, we obtained a detailed magnetic phase diagram for iron-rich ErFexMn12\u2212x series alloy samples with a fine composition increment (\u0394x = 0.2), and studied the exchange bias effect and magneto-caloric effect of samples. ErFexMn12\u2212x series (x = 7.0\u20139.0, \u0394x = 0.2) alloy samples were synthesized by arc melting, and the pure ThMn12-type phase structure was confirmed by X-ray diffraction (XRD). The neutron diffraction test was used to confirm the Mn atom preferentially occupying the 8i position and to quantify the Mn. The magnetic properties of the materials were characterized by a comprehensive physical property measurement system (PPMS). Accurate magnetic phase diagrams of the samples in the composition range 7.0\u20139.0 were obtained. Along with temperature decrease, the samples experienced paramagnetic, ferromagnetic changes for samples with x &lt; 7.4 and x &gt; 8.4, and paramagnetic, antiferromagnetic and ferromagnetic or paramagnetic, ferromagnetic and antiferromagnetic changes for samples with 7.4 \u2264 x \u2264 8.2. The tunable exchange bias effect was observed for sample with 7.4 \u2264 x \u2264 8.2, which resulting from competing magnetic interacting among ferromagnetic and antiferromagnetic sublattices. The maximum magnetic entropy change in an ErFe9.0Mn3.0 specimen reached 1.92 J\/kg\/K around room temperature when the magnetic field change was 5 T. This study increases our understanding of exchange bias effects and allows us to better control them.<\/jats:p>","DOI":"10.3390\/nano12091586","type":"journal-article","created":{"date-parts":[[2022,5,8]],"date-time":"2022-05-08T21:31:20Z","timestamp":1652045480000},"page":"1586","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Structure and Magnetic Properties of ErFexMn12\u2212x (7.0 \u2264 x \u2264 9.0, \u0394x = 0.2)"],"prefix":"10.3390","volume":"12","author":[{"given":"Penglin","family":"Gao","sequence":"first","affiliation":[{"name":"School of Mathematics and Physics, University of Science and Technology Beijing, Beijing 100083, China"},{"name":"Key Laboratory of Neutron Physics and Institute of Nuclear Physics and Chemistry, China Academy of Engineering Physics, Mianyang 621900, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuanhua","family":"Xia","sequence":"additional","affiliation":[{"name":"Key Laboratory of Neutron Physics and Institute of Nuclear Physics and Chemistry, China Academy of Engineering Physics, Mianyang 621900, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jian","family":"Gong","sequence":"additional","affiliation":[{"name":"Key Laboratory of Neutron Physics and Institute of Nuclear Physics and Chemistry, China Academy of Engineering Physics, Mianyang 621900, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xin","family":"Ju","sequence":"additional","affiliation":[{"name":"School of Mathematics and Physics, University of Science and Technology Beijing, Beijing 100083, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2022,5,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"449","DOI":"10.1107\/S0365110X52001337","article-title":"Compounds of Thorium with Transition Metals.
