Abstract
In NMR experiments the orbital p-wave pairing of He-3 atoms leads to the cr eation of magnetic supercurrents transferring magnetization within He-3 sam ple. These supercurrents are, together with dipole-dipole interaction, resp onsible for the generation of a macroscopic quantum coherently precessing s tate called homogeneously precessing domain (HPD). The HPD is the first exp erimental evidence of the phenomenon of magnetic superfluidity which is in full analogy with the mass superfluidity of He-4 and the superfluidity of e lectrons in superconductors. We present results of measurements of HPD by c ontinuous nuclear magnetic resonance (cw NMR) in nonhydrodynamic regime at a pressure of 0.6 MPa as well as the first results of numerical simulations of the HPD growth in "magnetically nonwetting" conditions.
