[institut] Семинар Центра за физику чврстог стања и нове материјале

[Nenad Lazarevic]

Поштоване колегинице и колеге,

Проф. др Чедомир Петровић, Condensed Matter Physics, Brookhaven 
National Laboratory, одржаће семинар под насловом:

"Superconducting and Normal States in Iron Chalcogenides"

у уторак 23. јуна, са почетком у 12 часова, у читаоници ИФ-а.

Резиме:

Iron based superconductors have been attracting considerable attention 
since their discovery in 2008 [1]. In particular, alkali-doped iron 
selenide materials have recently emerged to the frontier of research due 
to critical temperatures(Tc’s) that exceed Tc’s in iron arsenides [2,3]. 
In this talk I will discuss the
insulating states caused by high magnetic fields [4-5] or chemical 
substitutions. The discussion will be centered on the peculiarities of 
the crystal structure
[6-10], phase separation and on comparison with binary iron selenide 
superconductors [11].
