• Self-assembled Oxides

  We are studying BiFeO3/CoFe2O4 oxide composite thin films which have the remarkable characteristic of self assembling into vertical nanostructures during their deposition on a single crystal substrate, typically SrTiO3...

  
  

• Magnetic Logic

  We are interested in using ferromagnetic materials to engineer more energy efficient transistors and logic gates.  Transistors today are limited by the energy dissipated per switching operation, and this can potentially be greatly reduced by using a collective effect, such as the collective switching of magnetic moments...

  
  

• 360° Domain Walls

  Many domain wall (DW) devices require the presence of multiple DWs, each of which may need to be independently controlled and moved. So, we are investing the interaction of domain walls in a single ferromagnetic nanowire...

  
  

• Modeling Block Copolymers

  Block copolymer self-assembly on nanolithographically-defined templates has great potential in fabricating patterned media and devices at the nanometer scale. Current experimental work requires templates to first be written lithographically...

  
  

• Garnet for Magneto-Optical Devices

  We have been using pulsed-laser deposition to deposit a variety of oxide films for magneto-optical devices such as isolators. The ideal material for an isolator combines high Faraday rotation with high optical transparency...

  
  

• Magnetic Ring

  We are investigating the fabrication and magnetic properties of rings for magnetic logic and memory devices. The magnetic multilayer rings show giant magnetoresistance, in which the resistance is a function of the relative orientation of the magnetization...

  
  

• Block Copolymer Templated Self-assembly

  Self-organized macromolecular materials can provide an alternative pathway to conventional lithography for the fabrication of devices on the nanometer scale. In particular, the self-assembly of the microdomains of diblock copolymers...

Welcome to the Magnetic Materials & Devices Group

The Ross Group at MIT's Department of Materials Science carries out research in thin film magnetism, magnetic device, and self-assembly. Our current research includes
- magnetic devices for memory and logic
- magnetooptical materials for integrated photonic devices
- templated self-assembly of block copolymers for nanolithography
- templated self-assembly of heterostructured oxide and metal film dewetting
- deposition of films using sputtering, evaporation and pulsed laser deposition.
We are located in Building 13 of the MIT Campus.
