Abstract: In this paper we report about the properties of Neutron Transmutation Doped (NTD) Ge in magnetic fields, focusing on the electrical conduction properties and magnetoresistance, in view of a use as sensors for bolometers in magnetic field. Samples of two different doping density were studied in magnetic field up to 5 T and temperature down to 65 mK. NTD sensors show a reproducible gigantic magnetoresistance that leads to an enhancement of their sensitivity to temperature variations. We discuss preliminarily the possible use of NTD sensors in magnetic field in particle detector developments, in particular for the KATRIN experiment.
