Measurements of the magnetic Kapitza resistance between single crystals of CMN and lanthanum-diluted CMN in contact with ultrapure liquid3He are presented. The investigations were performed in the temperature range 2–100 mK and in magnetic fields up to 600 Oe. For the first time, a magnetic thermal coupling between bulk crystals with dimensions of up to 3 mm and liquid3He was observed. In the case of pure CMN and liquid3He below 7 mK, the relationR ∞ T n withn=4±1 is seen. A strong dependence ofR with magnetic field and Ce3+ content is found.
