Introduction

• Spintronicsattracting attention because of its
  potential applicability to new functional devices
  combining transport and magnetic properties.
• Magnetic semiconductors long history of research

History of Magnetic Semiconductors

• First generation chromium chalcogenide spinels
  and europium chalcogenides
• Second generation II-VI based diluted magnetic
  semiconductors (II-VI DMS) ?optical devices
• Third generation III-V based diluted magnetic
  semiconductors (III-V DMS)?electronic devices
• Fourth generation room-temperature ferromagnetic
  semiconductors
