The point group symmetry, mm2, of \u03b1-Cu2V2O7 possesses lower symmetry than the symmetry of its unit cell, hence, it is possible for the coexistence of an inversion domain in this material. The works on \u03b1-Cu2V2O7, however, have never clearly shown that the crystal under consisted of single domain. In this work we focused on a Bridgman-grown single crystal X-ray diffraction study of \u03b1-Cu2V2O7 in order to reveal its crystallographic domain and also to determine its absolute structure. Our result confirm that the Bridgman-grown \u03b1-Cu2V2O7 crystal consists of single domain.<\/p>\n<p>We believe that this work would be a great interest to researchers studying physical properties on \u03b1-Cu2V2O7 as it provides necessary informations for understanding ferroelectric and nonreciprocal properties, as well as to the broad community of condensed matter physicists.<\/p>\n<p>(Pharit Piyawongwatthana)<\/p>\n<div><a class=\"rm-cv-list-title\" href=\"https:\/\/researchmap.jp\/7000012554\/published_papers\/31543603\">Formation of Si<\/a><a href=\"https:\/\/doi.org\/10.7566\/jpsj.90.025003\">ngle Polar Domain in \u03b1-Cu2V2O7\u00a0<\/a><\/div>\n<div class=\"rm-cv-list-author\">Pharit Piyawongwatthana, Daisuke Okuyama, Kazuhiro Nawa, Kittiwit Matan, Taku J.
