The conceptualization conceived by Megaw relied on the profound analysis of the crystallographic data obtained for LN (Bailey, 1952 [74]) and ilmenite (Barth and Posnjak, 1934 [100]). Disregarding specifics, she concluded that whereas the changeover paraelectric-ferroelectric in LN is continuous and reversible, implying even so large atomic displacements of the https://shanehnqqq.total-blog.com/5-easy-facts-about-lithium-niobate-crystal-described-57732558
