The magnetic effective exchange interactions were calculated using <jats:italic>ab-initio<\/jats:italic> methods explicitly treating the electronic correlation. A model Hamiltonian (quantum Heisenberg Hamiltonian, and for comparison a spin 1\/2 Ising Hamiltonian) was built from these interactions and used to determine the zero temperature magnetic order versus magnetic field.

The magnetization versus magnetic field reveals the existence of a 1\/3 plateau that could be observed in high-pulsed magnetic field experiments.

We believe that this non-frustrated behavior could also take place in other triangular copper-based systems.<\/jats:p>","DOI":"10.1088\/1361-648x\/ad5d39","type":"journal-article","created":{"date-parts":[[2024,6,28]],"date-time":"2024-06-28T18:29:42Z","timestamp":1719599382000},"page":"415803","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Why the pyrochlore-like antiferromagnet NaCu<sub>3<\/sub>F<sub>7<\/sub> is magnetically non-frustrated"],"prefix":"10.1088","volume":"36","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5157-0236","authenticated-orcid":true,"given":"Julien","family":"L\u00e9v\u00eaque","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5709-5547","authenticated-orcid":false,"given":"Elisa","family":"Rebolini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8730-4282","authenticated-orcid":true,"given":"Marie-Bernadette","family":"Lepetit","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0540-703X","authenticated-orcid":true,"given":"Andr\u00e9s","family":"Sa\u00fal","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"266","published-online":{"date-parts":[[2024,7,15]]},"reference":[{"key":"cmad5d39bib1","doi-asserted-by":"publisher","first-page":"603","DOI":"10.1016\/0022-4596(88)90156-9","volume":"73","author":"Renaudin","year":"1988","journal-title":"J.
