Abstract

Single crystals of monoclinic La5Co2Ge3 were grown using a self-flux method and were characterized by room-temperature powder X-ray diffraction, anisotropic temperature and field dependent magnetization, temperature dependent resistivity, specific heat, and muon spin rotation. La5Co2Ge3 has a Curie temperature (TC) of 3.8~K and clear signatures of ferromagnetism in magnetization and μSR data, as well as a clear loss of spin disorder scattering in resistivity data and a sharp specific heat anomaly. The magnetism associated with La5Co2Ge3 is itinerant, has a change in the entropy at TC of ≃0.05 R ln2 per mol-Co, and has a low-field saturated moment of ∼0.1μB/Co, making it a rare, itinerant, small moment, low TC compound.
