We created a hybrid structure using cobalt and permalloy micromagnets to control electron spin. Spin effects in ballistic transport were observed, linked to Zeeman and Stern-Gerlach modes.

Area of Science:

  • Spintronics
  • Condensed Matter Physics
  • Materials Science

Background:

  • High-mobility electron systems like GaAs/AlGaAs interfaces are crucial for advanced electronics.
  • Controlling electron spin is a key goal in spintronics for novel device applications.
  • Local magnetic potentials can influence electron spin states.

Purpose of the Study:

  • To fabricate a hybrid structure for generating a local in-plane spin-dependent potential barrier.
  • To investigate spin effects in ballistic electron transport at the GaAs/AlGaAs interface.
  • To understand the influence of external magnetic fields on spin-dependent transport phenomena.

Main Methods:

  • Fabrication of a hybrid structure integrating cobalt and permalloy micromagnets.
  • Utilizing high-mobility GaAs/AlGaAs heterostructures.
