Thermal conductivity (kappa), heat capacity (CP), magnetization (M) and electrical resistivity (rho) of the Ni50.2Mn39.1In10 Heusler alloy were measured in wide temperature range of T=25-350 K. Anomalies were found on the M(T) and CP(T) curves, indicating phase transitions of the second and first order with the Curie temperature TC=322 K and the temperature of the martensitic transition start MS=296 K. A sharp increase in thermal conductivity Δkappa=3.2 W/(m · K) during the martensite-austenite transition is found, caused by the electron contribution due to the electron mobility increasing during the transition to the more symmetric phase. The lattice thermal conductivity changes insignificantly during the transition, that indicates the insensitivity of phonons to the structural disorder. Keywords: Heusler alloys, ferromagnetic, magnetostructural phase transitions, helium temperatures, resistivity, magnetization.
