講座題目:物理學與信息技術學院“70周年校慶系列講座”暨恒元物理學講座(第030期):Degrees of freedom in the functionalization of laser-induced, ultrafast spin dynamics

講座人:Dr. Georgios Lefkidis(德國凱澤斯勞滕工業(yè)大學)

講座時間:16:30

講座日期:2014-9-24

地點:長安校區(qū) 物理學與信息技術學院六層學術報告廳(致知樓3623-3624)

主辦單位:物理學與信息技術學院

講座內(nèi)容:After the discovery of laser-induceddemagnetization[1] the optical manipulation of the magnetic state of materialshas become an increasing field of research. In this talk a brief report of somemore recent advances will be given[2], followed by a discussion pertinent tothe design of magnetic structures whose purpose is the coherent magneto-opticalcontrol. The main focus of the talk will be on how to take into account thedifferent degrees of freedom in the calculations, as well as how to activelyuse them when designing spintronics materials. After a short description of thepursued concepts, the spin, the phonons[3], the laser parameters and finallythe temperature will be addressed. At the same time some of the delicateinterplays between those degrees of freedom will be pointed out, combined withthe description of how to use them in order to devise spin-dependent heatengines on the nanoscale[4].
