主　　题：Antiferromagnetic imaging Magnetic lattice Ptychography Electron microscopy 

摘      要：Antiferromagnetic imaging is critical for understanding and optimizing the properties of antiferromagnetic materials and *** the widespread use of high-energy electrons for atomic-scale imaging,they have low sensitivity to spin ***,the magnetic contribution to the phase of a highenergy electron wave is weaker than one percent of the electrostatic ***,we demonstrate direct imaging of antiferromagnetic lattice through precise phase retrieval via electron ptychography,paving the way for magnetic lattice imaging of antiferromagnetic materials and devices.
