Imprinting spin patterns by local strain control in a van der Waals antiferromagnet
Zhuoliang Ni, Huiqin Zhang, Qi Tian +6
Van der Waals magnets provide opportunities for exploring low-dimensional magnetism and spintronic phenomena. The Mermin-Wagner theorem states that long-range correlations in reduc…
Magnetic field control of continuous Néel vector rotation and Néel temperature in a van der Waals antiferromagnet
Zhuoliang Ni, Urban Seifert, Amanda V. Haglund +4
In a collinear antiferromagnet, spins tend to cant towards the direction of an applied magnetic field, thereby decreasing the energy of the system. The canting angle becomes neglig…
Observation of giant surface second harmonic generation coupled to nematic orders in the van der Waals antiferromagnet FePS
Zhuoliang Ni, Nan Huang, Amanda V. Haglund +2
Second harmonic generation has been applied to study lattice, electronic and magnetic proprieties in atomically thin materials. However, inversion symmetry breaking is usually requ…
Direct imaging of antiferromagnetic domains and anomalous layer-dependent mirror symmetry breaking in atomically thin MnPS
Zhuoliang Ni, Huiqin Zhang, David Hopper +8
We have developed a sensitive cryogenic second-harmonic generation microscopy to study a van der Waals antiferromagnet MnPS. We find that long-range Néel antiferromagnetic orde…
Imaging the Néel vector switching in the monolayer antiferromagnet MnPSe with strain-controlled Ising order
Zhuoliang Ni, A. V. Haglund, H. Wang +7
The family of monolayer two-dimensional (2D) materials hosts a wide range of interesting phenomena, including superconductivity, charge density waves, topological states and ferrom…
