Dramatic depression of Curie temperature for magnetic Co/Cu(100) ultrathin films upon deposition at elevated temperature
No full textThe correlation between the crystalline structures & magnetic properties, such as magnetization & Curie temperature (TC) were investigated systematically by varying the deposition temperature of 2 ML fcc cobalt films on Cu(1 0 0) substrate. At variation of the deposition temperature a dramatic change in Curie temperature & coercivity of the films was observed. The drastic raising of Curie temperature were found for the films with the deposition temperatures from 340 K (TC ¼ 170 K) down to 275 K (TC ¼ 325 K). A simple theoretical estimation was proposed to evaluate the Curie temperature of the films in terms of magnetic moment as well as anisotropy with quantitative success. The enhanced Curie temperature can be attributed to the increase of the magnetic moments due to the alteration of film morphology with various deposition temperatures
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
