Effect of Magnetic Plane Defects on Thermal Conductivity of Solid 3He in U2D2 Phase
We calculate the thermal conductivity of solid 3He in U2D2 phase. In this system, magnons are the dominant heat carriers. The experiment by Feng et al. shows that scattering magnon by some kind of magnetic defects becomes important at low temperature. We suppose the defects are the magnetic plane defects (MPD) which are originated by lattice dislocation and calculate the thermal conductivity with Kapitza Resistance Model (KRM).
