Stability of antiferromagnetism at high magnetic fields in Mn3Si

Abstract

We report low temperature measurements of the specific heat, resistivity and magnetisation of the itinerant antiferromagnet Mn3Si. The unprecedented stability of the magnetic state to high magnetic field up to 14 T inferred from the invariance of these bulk properties is incompatible with itinerant magnetism expected of a conventional Fermi liquid.
