Metallic Magnetic Hetrostructures
This work studied sputter deposited conventional spin valves (SV) and related structures. In SV layered structures, two ferromagnetic layers are separated by a non-magnetic spacer. Under an external magnetic field, the relative orientation of the magnetization changes in the ferromagnets, …

Microplasticity in metallic glasses
Metallic Glasses (MGs) are amorphous metallic alloys with exceptional mechanical and physical properties. Like all good things, this class of materials comes with its own problems, in this case (i) a lack of ductility, (ii) degradation in properties over time due to aging, and (iii) abrupt and …

Thermomechanical Processing of Metallic Glasses
Depending on its thermal and kinetic history, a metallic glass (MG) of a given composition can show a wide range of energetic states. One central parameter determining the initial state of a glass is the cooling rate used to form it upon quenching from the melt. A faster cooling rate will give rise …
