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.
