By spark-eroding Fe75Si15B10 in water/ethanol mixtures, spherical particles with nanostructured cores consisting of mixed amorphous and crystalline phases were produced. The relative volume fractions of the amorphous and crystalline phases were depen

Spark erosion is an extremely versatile method for producing particles of almost any type of material, in particle sizes ranging from a few nm to >100 μm. The general features of spark erosion, its application to the production of amorphous soft mag

Nanoparticles of ferrimagnetic NiFe2O4 and antiferromagnetic NiO exhibit a variety of anomalous magnetic properties. The lower coordination of surface spins is responsible in both cases for the observed behavior. This conclusion is supported by calcu

Rapidly quenched (Co95Fe5)1-xAlx ribbons are investigated by X‐ray diffraction, magnetization, and Mossbauer effect measurements. A single fcc phase is obtained for all ribbons x ⩽ 10 at.%. The lattice constant increases linearly with x and is di
