A thermodynamically stable phase separation of Co 2Dy 0.5Mn 0.5Sn into the Heusler compound Co 2MnSn and Co 8Dy 3Sn 4 is induced by rapid cooling from the liquid phase. The phase separation forms an ordered flower-like structure on the microscale. The increased scattering of phonons at the phase boundaries reduces the thermal conductivity and thus improves thermoelectric and spincaloric properties.
