Research front maps are diagrammatic representations of the core papers
comprising each front. They are selected from the current Research Front set
that are relevant to the featured special topic. The title for this Research
Front Map is "UNCONVENTIONAL COBALT OXIDE SUPERCONDUCTORS," containing 32
core papers. Source dates: 1998-August 31, 2008 (fifth bimonthly
period 2008).
Each circle represents a highly cited paper whose bibliographic information
is displayed when the user clicks on the circle. The solid lines between circles
represent the strongest co-citation links for each paper (that is, indicating
that the papers are frequently cited together); weaker links are indicated by
dashed lines. Papers close to each other on the map are generally more highly
co-cited. The most recent paper(s) are indicated in pink. Annotations may have
been added to this map which represent the main research themes. These appear as
labels attached to specific regions on the maps.
Note: For best results use the
"landscape orientation" option when printing this page.
