我们研究了Cr₃P、Mn₃P、Fe₃P和Ni₃P以及这些化合物相互之间的固溶体的磁矩对温度的依赖性。这些测量结果表明，Ni₃P和Cr₃P具有与温度无关的泡利型顺磁性。基于高温磁化率，Mn₃P是反铁磁性的（TN≈115K），Mn的磁矩为1.68μB。Fe₃₋ₓCoₓP（x高达0.6）的固溶体表明，Co贡献了一个1.6μB的磁矩，与铁呈铁磁性排列。在Fe₃₋ₓNiₓP体系中，对于所有的x值，镍都起到稀释剂的作用。Fe₃₋ₓMnₓP（x高达1.5）的固溶体也能够形成；在这种情况下，反铁磁性有序显著降低了磁矩。M₃P系列的磁矩随成分的变化与斯莱特 - 鲍林曲线非常相似。
We have investigated the temperature‐dependence of the magnetic moment of Cr3P, Mn3P, Fe3P and Ni3P including solid solutions of these compounds with each other. These measurements indicate Ni3P and Cr3P have a temperature‐independent Pauli‐type paramagnetism. Mn3P is antiferromagnetic (TN≈115°K) with a moment of 1.68 μB for Mn based on the high‐temperature susceptibility. Solid solutions of Fe3−xCoxP up to x=0.6 show that Co contributes a moment of 1.6 μB ferromagnetically aligned with the iron. In the Fe3−xNixP system, nickel acts as a diluent for all values of x. Solid solutions of Fe3−xMnxP up to x=1.5 could also be formed; in this case, antiferromagnetic ordering lowers the magnetic moment significantly. The variation of the magnetic moments with composition for the M3P series closely resembles the Slater‐Pauling curve.
