3He is an example of the system with non-trivial Cooper
paring. A few different superfluid phases are known in this system.
Recently the new one, the polar phase, have been observed in 3He
confined in nematically ordered aerogel. A number of various topological
defects including half-quantum vortices can exist the polar phase. In
this work we present theoretical and numerical studies of linear nuclear magnetic resonance in
the polar phase both in the uniform order-parameter texture and in the
presence of half-quantum vortices.
