Recently, the group of Demokritov discovered room-temperature Bose-Einstein condesates (BEC) of magnons in the well-known magnetic insulator Yttrium Iron Garnet (YIG). I will describe the experiment and then show that by changing the field configuration in it, so that the inter-magnon interactions change, the BEC ought to stabilise at a density some 4-5 orders of magnitude higher than at present. This system ought to possess some very interesting properties.
