A Stable CrO₂ Nanoparticle and A Process for Its Manufacture.

The process is for the production of stable granular GMR materials of CrO₂ nanoparticles. These can be used in magnetic memory devices and more particularly in a magnetic random access memory for writing information with a reduced write-current. It also relates to the process for preparing stabilized CrO₂ in form of a finely divided loose powder suitable for fabricating small devices and components in a specific shape or size.

Spintronics with good GMR, Optical and Magnetic properties.

• The raw materials are readily available and cost effective.
• It also provides stabilized CrO₂ having excellent and improved GMR properties than those achieved in conventional CrO₂.Therefore it is possible to extend the use/application of such CrO₂ in magnetic memories ,magnetic disc drives and other devices.
• It provides a viable method for processing of stabilized CrO₂ ceramics and composites.
