Above the temperature of the GB wetting phase transition a GB cannot exist in equlibrium with the liquid bulk phase. The liquid phase has to substitute the GB and to separate both grains.

The GB wetting tie line can continue in the one-phase area of the bulk phase diagram as a GB solidus line. This line represents the GB premelting or prewetting phase transitions. The GB properties change drastically when the GB solidus line is crossed by a change in the temperature or concentration.

Thin films of La0.67Ca0.33MnO3 on a SrTiO3(100) substrate, with a misfit of 1.54% (aF<aS), exhibit a remarkable microstructure. In direct contact with the SrTiO3 substrate a thin perfectly coherent La1−xCaxMnO3 layer, which exhibits a slightly distorted monoclinic symmetry, is formed. On top of this first layer a second thicker layer is grown; it has a columnar microstructure. For epitaxial La0.7Sr0.3MnO3(LSMO) films on a LaAlO3(001) substrate the evolution of stress (2.77%, aF>aS) in the film is function of film thickness and thermal treatment. Thin films (20 nm) are accommodated elastically. In thicker films the stress is partially relieved after annealing by the formation of a network of misfit dislocations with an edge character. For epitaxial La0.9Sr0.1MnO3 films on SrTiO3 (100) the small misfit (aF≈aS) is accommodated either purely elastically (for thin film) or by the formation of periodic microtwins.</div>","PeriodicalId":100700,"journal":{"name":"International Journal of Inorganic Materials","volume":"3 8","pages":"Pages 1331-1337"},"PeriodicalIF":0.0,"publicationDate":"2001-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/S1466-6049(01)00155-6","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90594717","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Chromium oxide films on nickel-coated copper metallic substrates have been deposited from a chromate bath.
