Both are superstructures of the rosiaite type (space group P3\u00af1c). Their thermodynamic properties have been investigated by means of magnetization M and specific heat Cp measurements, evidencing the formation of the long-range antiferromagnetic order at TN = 2.4 K in the former compound and paramagnetic behavior down to 2 K in the latter compound. Large magnetocaloric effect allows considering GdFeTeO6 for the magnetic refrigeration at liquid hydrogen stage. Density functional theory calculations produce estimations of leading Gd\u2013Gd, Gd\u2013Fe and Fe\u2013Fe interactions suggesting unique chiral 120\u00b0 magnetic structure of Fe3+ (S = 5\/2) moments and Gd3+ (J = 7\/2) moments rotating in opposite directions (clockwise\/anticlockwise) within weakly coupled layers of the rosiaite type crystal structure.<\/jats:p>","DOI":"10.3390\/ma14205954","type":"journal-article","created":{"date-parts":[[2021,10,10]],"date-time":"2021-10-10T21:37:29Z","timestamp":1633901849000},"page":"5954","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Chirality and Magnetocaloricity in GdFeTeO6 as Compared to GdGaTeO6"],"prefix":"10.3390","volume":"14","author":[{"given":"Elena","family":"Zvereva","sequence":"first","affiliation":[{"name":"Department of Low Temperature Physics and Superconductivity, Physics Faculty, Lomonosov Moscow State University, 119991 Moscow, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3385-5801","authenticated-orcid":false,"given":"Tatyana","family":"Vasilchikova","sequence":"additional","affiliation":[{"name":"Department of Low Temperature Physics and Superconductivity, Physics Faculty, Lomonosov Moscow State University, 119991 Moscow, Russia"}]},{"given":"Maria","family":"Evstigneeva","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Southern Federal University, 344090 Rostov-on-Don, Russia"}]},{"given":"Angelica","family":"Tyureva","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Southern Federal University, 344090 Rostov-on-Don, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8624-0165","authenticated-orcid":false,"given":"Vladimir","family":"Nalbandyan","sequence":"additional","affiliation":[{"name":"Department of Chemistry, Southern Federal University, 344090 Rostov-on-Don, Russia"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9057-378X","authenticated-orcid":false,"given":"Jo\u00e3o","family":"Gon\u00e7alves","sequence":"additional","affiliation":[{"name":"Department of Physics and CICECO, University of Aveiro, 3810-193 Aveiro, Portugal"}]},{"given":"Paolo","family":"Barone","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche, Institute for Superconducting and Innovative Materials and Devices (CNR-SPIN), Area della Ricerca di Tor Vergata, Via del Fosso del Cavaliere 100, I-00133 Rome, Italy"}]},{"given":"Alessandro","family":"Stroppa","sequence":"additional","affiliation":[{"name":"Consiglio Nazionale delle Ricerche, Institute for Superconducting and Innovative Materials and Devices (CNR-SPIN), c\/o Department of Physical and Chemical Sciences, University of L\u2019Aquila, Via Vetoio Coppito, I-67100 L\u2019Aquila, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3558-6761","authenticated-orcid":false,"given":"Alexander","family":"Vasiliev","sequence":"additional","affiliation":[{"name":"Department of Low Temperature Physics and Superconductivity, Physics Faculty, Lomonosov Moscow State University, 119991 Moscow, Russia"},{"name":"Quantum Functional Materials Laboratory, National University of Science and Technology \u201cMISiS\u201d, 119049 Moscow, Russia"}]}],"member":"1968","published-online":{"date-parts":[[2021,10,10]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"18","DOI":"10.1038\/s41535-018-0090-7","article-title":"Milestones of low-D quantum magnetism","volume":"3","author":"Vasiliev","year":"2018","journal-title":"NPJ Quantum Mater."},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"203","DOI":"10.1063\/1.1884423","article-title":"Spin gap in low-dimensional magnets","volume":"31","author":"Markina","year":"2005","journal-title":"Low Temp.
