N2 - The magnetic properties of the icosahedral phase and the effect of B on the appearance of its ferromagnetism were examined for icosahedral Al70-xPd15Mn15Bx (X = 0-6 at.%) alloys. On the assumption that the magnetic moment is composed of Curie-Weiss paramagnetism, Pauli paramagnetism and ferromagnetism, the 1/X-T curve can be filled well with the experimental data. The agreement seems to be because the magnetic moment due to the Curie-Weiss paramagnetism is much larger than that due to the ferromagnetism and the number of atomic pairs having the Curie-Weiss paramagnetic component is about twice as large as that for the ferromagnetic component. Furthermore, the constituent ratios of each magnetic component as a function of B content were derived by fitting the model to the experimental data. The increase in B content to above 3 at.% causes an increase in ferromagnetic and Curie-Weiss paramagnetic components and a decrease in the Pauli paramagnetic component.
