Workshop on CMR Manganites

and Related Transition Metal Oxides

Telluride, Colorado, July 14-20, 2002

Future Trends in CMR

 

Following are some questions and future areas of investigation that the Workshop participants consider important to address:

 

 

  1. How homogeneous is the metallic state?
  2. What is the relationship between the exchange interaction and TC? What is the balance between double exchange and superexchange?
  3. What is the nature of the ferromagnetic insulating state (w/wo charge order?)
  4. Is phase separation intrinsic to CMR?
  5. How should “correlated polarons” be described theoretically?
  6. How can we control disorder?
  7. Can spin transport devices be constructed where the doping is controlled electronically?
  8. What controls the spin-flip scattering at interfaces and surfaces?
  9. What is the role of orbital ordering in the phase diagram?
  10. Is there a “real” “pseudogap” in the CMR materials, in analogy with the cuprates?
