In the systems Au&sngbnd;Ni and &bgr;‐brass‐Fe, ferromagnetic precipitate particles develop in a nonmagnetic matrix. Single crystal samples of these alloys have been examined by measuring saturation magnetization, torque curves, rotational hysteresis, and remanence.The data on the Au&sngbnd;Ni system have been analyzed to infer particle anisotropy distributions, orientation of the ``easy'' axes of the particles, and other features of the precipitate particle system. Electron micrographs of the precipitate particles are in general agreement with this analysis. The measurements on the &bgr;‐brass‐Fe system indicated that the precipitate particles were single crystals with the same crystal habit as the matrix, and were elongated in the ⟨111⟩ directions. The temperature dependence of the torque curves was identified with the temperature dependence of shape and magnetocrystalline anisotropy.
