The phase composition,magnetic properties i.e.coercivity and the magnetic polarization at room temperature for the bulk Fe67Co5Nd3Y6B19 and Fe64Co5Nd6Y6B19 alloys were studied.The bulk amorphous Fe67Co5Nd3Y6B19 alloy,inhomogeneous in the as-quenched state,crystallized after annealing at 948 K for 0.5 h and consisted of Nd2Fel4B-type,Fe2B and paramagnetic phases.The rapidly solidified Fe67Co5Nd3Y6B19 alloy contained the Nd2Fe14B-type and paramagnetic phases.The annealing of the bulk Fe67Co5Nd3Y6B19 alloy at 948 K for 0.5 h led to hard magnetic properties.However,the bulk Fe67Co5Nd3Y6B19 alloy exhibited good hard magnetic properties directly after preparation.
