讲座内容摘要:
The discovery of 2D magnetic materials opens a new avenue for the next generation ofspintronic materials and devices. Here we are going to show the epitaxial growth of novel 2Dmagnetic materials CrTe2 and Fe3GaTe2 on GaAs (111)B substrates by molecular beamepitaxial. The ultra-thin filmsdemonstrate out-of-plane magnetism with a Curie temperature upto 380K. The magnetism of the 2D materials can be tuned by doping and/or gate voltages.Furthermore, novel electronic devices based on 2D magnetic materials have been synthesizedand fabricated. Interesting phenomena, such as the topological Hall effect due to the formationof skyrmion,current-driven magnetism switching due to the spin-orbital torques (SOT), and three-state magnetic storage devices, have been demonstrated. The results suggest that novel 2D magnetic materials could be the critical building blocks for quantum computation and storage.
