nanomagnetsTuesday, 13 December 2022, 10:00, KFKI Campus, Bldg. 1, 2nd floor, 
Conference RoomMagnetic materials play an important role in conventional data 
storage and information processing devices due to the exceptional stability 
of the magnetic state and their energy-efficient operation. As the system 
size approaches the nanometer scale and faster operations become necessary, 
thermal and quantum fluctuations progressively assume a pronounced role. 
While the fluctuations threaten the high stability of magnetic structures, 
they also give rise to fundamentally novel phenomena which may find 
applications in neuromorphic, stochastic or quantum computing paradigms.In 
this talk, I will give an overview of my recent theoretical research 
activities in the field of nanomagnetism. When the orientation of the 
magnetic moments changes on the atomic scale, non-collinear spin structures 
such as magnetic skyrmions are formed. The effect of thermal fluctuations on 
the movement and lifetime of skyrmions will be discussed. The excitations of 
magnetically ordered systems are known as magnons. The influence of thermal 
noise and dissipation on the magnon frequencies will be explored. When the 
nanoscale magnetic structures are brought in proximity of a conventional 
superconductor, Yu-Shiba-Rusinov bound states emerge. The role of the 
magnetic configuration on the energies of the Yu-Shiba-Rusinov states will be 
explained. Promising avenues for future research in this field will be 
summarized at the end.Join Zoom
