InSb doped with Mn offers an excellent integrated cryogenic detector for low-energy X-ray and beta spectroscopy. It combines good properties from both spectroscopic point of view (high atomic number) and low-temperature (LT) thermometry. The thermosensitivity is superiour over that of the most popular another bulk thermistor from neutron-transmutation-doped (NTD) Ge and its application is not restricted by the severe technological aspects. The results of (magneto)resistivity versus temperature R(T) and magnetic susceptibility X(T) measurements, performed to clear up an unusial behaviour of conductivity at mK temperatures, are presented.
