In the literature, research into rapidly cooled Pt-based alloys usually features samples that are produced in the form of thin ribbons. This work presents the effect of the addition of a small quantity of W and Pt on the magnetic properties of massive two-phase alloys, the samples being produced in the form of plates with a thickness of 0.5 mm. Both amorphous and crystalline phases were observed in the alloys, the phase proportions depending on the composition of the alloy. Generally, it is assumed that alloys with added Pt are characterised by a relatively high saturation magnetization and magnetocrystalline anisotropy, which is mainly influenced by the presence of the crystalline phases: FePt and Fe₃Pt. For the investigated alloys, it was noted that the gradual substitution of W and Pt in place of Y within the alloy Fe₆₁Co₁₀B₂₀Y_{8-x}W_{y}Pt_{x} increased the value of saturation magnetization (μ₀M_{s}) and reduced the coercive field (H_{c}). On the basis of XRD pattern analysis it was found that, within the sample with the highest concentration of Pt, there are crystallites of the smallest size and the proportion of the α-Fe crystalline phase is much greater than for the other studied samples.
