We declare the observation of spin superfluid state in Yttrium Iron Garnet (YIG) at room temperature. It is similar to a Homogeneous Precessing State (HPD), observed earlier in antiferromagnetic superfluid $^3$He-B. The formation of this state explains by the repulsive interaction between magnons, which is required as a prior condition for the spin superfluidity. It establishes an energy gap, which stabilizes the long range superfluid transport of magnetization and determines the Ginzburg…

Long-Lived Induction Signal in Yttrium Iron Garnet

The results of the experiments on an yttrium iron garnet film have been reported, demonstrating two types of long-lived free induction signals. The first type corresponds well to signals appearing

Stability of Bose-Einstein condensates of hot magnons in yttrium iron garnet films.

It is predicted that a high-density room-temperature magnon BEC should form in this perpendicular field geometry if a strong field applied perpendicular to the sample plane leads to a repulsive magnon-magnon interaction.

Magnon condensation and spin superfluidity

Observation of a Time Quasicrystal and Its Transition to a Superfluid Time Crystal.

We report experimental realization of a quantum time quasicrystal and its transformation to a quantum time crystal. We study Bose-Einstein condensation of magnons, associated with coherent spin

Bose-Einstein Condensation of Magnons and Spin Superfluidity in the Polar Phase of ^{3}He.

It is suggested that the magnon BEC in the polar phase is a powerful probe for topological objects such as vortices and solitons and topological nodes in the fermionic spectrum.

Cavity quantum electrodynamics with ferromagnetic magnons in a small yttrium-iron-garnet sphere

Hybridizing collective spin excitations and a cavity with high cooperativity provides a new research subject in the field of cavity quantum electrodynamics and can also have potential applications to

Phonons in a magnon superfluid and symmetry-breaking field

Recent experiments [1,2] on the measurement of the spectrum of the Goldstone collective mode of a coherently precessing state in 3He-B are discussed using the presentation of the coherent-spin

Bogoliubov waves and distant transport of magnon condensate at room temperature

Experimentalally the condensed magnons forming compact humps of BEC density can propagate many hundreds of micrometers in the form of Bogoliubov waves, which advances the physics of quasiparticles and allows for the application of related transport phenomena for low-loss data transfer in magnon spintronics devices.

Persistent coherent spin precession in superfluid He-3-B driven by off-resonant excitation

In superfluid He-3-B under conditions of negligible normal fluid density we are able to trap a domain of coherent spin precession away from the destructive influence of boundaries. After the domain
