Abstract: Abstract: AC-susceptibility measurements for HoCo3B2 show paramagnetism below room temperature and a small, and large anomalies at 150 and 10K, respectively. Neutron powder diffraction measurements show a ferromagnetic order below 10K, where the ferromagnetic Ho and Co sublattices are ferromagnetically coupled. The magnetic axis direction is perpendicular to the c axis. The observed magnitudes of the magnetic moments at 4.5K are 5.08(4) and 0.11(2) for Ho and Co, respectively. No long range magnetic order was detected above 10K. [Copyright &y& Elsevier]
