Magnon BEC at room temperature
LTL Quantum Physics Seminar (Nanotalo). Speaker: Prof. Yury Bunkov (Kazan federal University, Russia).
The main topic of this presentation is the current observation of magnon BEC in the YIG film at room temperature for k=0. This observation is similar to magnon BEC in antiferromagnetic superfluid 3He-B, discovered 30 years ago in the institute Kapitza, Moscow. This discovery makes a great potential for supermagnonic applications, which will be considered.
