Review: pure, amorphous iron

This is a review of glassy iron in its pure form, written in honour of Professor Kamanio Chattopadhyay’s distinguished career, particularly with respect to highly metastable materials. The review covers the difficulty in obtaining amorphous iron, the clever experiments that have produced small particles or thin films of glassy iron, together with models that estimate the process parameters and many other features of disorder. Magnetic properties are highlighted though not fully understood.
