Spintronics

Spintronics is a new technology in solid-state devices which exploits the intrinsic spin of electrons and its associated magnetic moment in addition to its fundamental electronic charge.

 

 

Nanoscale Domain Wall Devices

Magnetic domain walls can be manipulated in FM nanostructures by controlling some parameters like magnetocrystalline anisotropy and shape anisotropy, yielding rich physics and promising applications.
 
 

Spintronic Immunoassay and Biomagnetism

Live, real time detection of magnetic micro-beads and nano-wires using a MTJ sensor.

 

 

Half Metals: the Absolute Magnets

Systems with complete spin polarization, termed as half metallic because they are metallic for one spin direction while at the same time semiconducting for the other spin direction.



Ultrasensitive Magnetic Microsensors

Spintronics is a new technology in solid-state devices which exploits the intrinsic spin of electrons and its associated magnetic moment in addition to its fundamental electronic charge.



Scanning Magnetoresistive Microscope

This magnetic microscope uses a MR sensor as the sensing element. It offers submicron resolution and can image current carrying devices like ICs and other solid state devices.



Exchange Bias in Multilayers
Exchange coupling of ferromagnetic and antiferromagnetic films across their common interface causes a shift in the hysteresis loop of the ferromagnet - a phenomenon known as exchange bias.



Micromagnetics and Interlayer Coupling
Spintronics is a new technology in solid-state devices which exploits the intrinsic spin of electrons and its associated magnetic moment in addition to its fundamental electronic charge.



Extraordinary Hall Effect
Ferromagnets display the extraordinary Hall effect, an additional contribution which depends directly on the magnetization of the material and is often much larger than the ordinary Hall effect.



MTJ Sensor Array
MTJs are magnetic sensors which consist of two ferromagnetic layers separated by an extremely thin insulating layer.
