Abstract

Over the last two decades, nanocrystalline materials were investigated for applications in magnetic devices. The benefits of nanocrystalline alloys stem from their chemical and structural variations over nanometer scale which are important for developing optimal magnetic properties. Over the last decade less attention has been paid to the stability of nanostructured materials under extreme conditions of pressure and temperature. The main aim of the present work is to study the behaviour of soft magnetic nanostructured Fe88Zr7B4Cu1 (NANOPERM) alloy under high pressure – high temperature conditions. The αFe (bcc) crystalline cell at 5000C for pressures up to 3.5 GPa was evaluated using synchrotron radiation X-ray diffraction..
