2D van der Waals (vdW) antiferromagnets have received intensive attention due to their terahertz resonance, multilevel magnetic-order states, and ultrafast spin dynamics. However, accurately identifying magnetic configuration still remains a challenge owing the lack of net magnetization insensitivity external fields. In this work, Néel-type antiferromagnetic (AFM) order in antiferromagnet VPS3 with out-of-plane anisotropy, which is demonstrated by temperature-dependent spin-phonon coupling...
Two-dimensional (2D) ferroelectrics has emerged as a promising building block for nonvolatile memory devices. In this work, we demonstrate the out-of-plane ferroelectricity of 2D CuCrP2S6 (CCPS) at room temperature and switchable diode effect in CCPS-based ferroelectric nanodevices. The spontaneous polarization switching hysteresis loops are directly evidenced by piezoresponse force microscopy. intrinsic originates from non-centrosymmetric structure CCPS, which is confirmed optical...
Abstract A comprehensive study of 2D magnetic ordering mediated second harmonic generation (SHG) is essential for a thorough understanding symmetry and its potential nonlinear applications. Here, an extraordinarily large FM‐mediated SHG demonstrated in CrPS 4 , which possesses both spatial time‐reversal breaking. The inversion breaking gives rise to i‐type response. In contrast, the antiferromagnetic (AFM) bulk even‐numbered layers do not produce any magnetism‐mediated c‐type SHG....
Polar metals, a family of materials with exclusive but coexisting electric polarization and metallicity, have attracted plenty studies recently. Experimentally, how these two states interact each other is still an open question thus far. Here, we report on the existence ferroelectric metal switchable unexpected high carrier density in Ba0.5La0.5TiO3 films. A combination atomic resolution scanning transmission electron microscopy, high-resolution x-ray diffraction, piezoresponse force optical...
As a crucial concept in magnetism and spintronics, exchange bias (ExB) measures the asymmetry hysteresis loop of pinned ferromagnet (FM)/antiferromagnet (AFM) interface. Previous studies are mainly focused on FM/AFM heterostructures composed conventional bulk materials, whose complex interfaces prohibit precise control full understanding phenomenon. Here, enabling power 2D magnets is exploited to demonstrate emergence, non-aging, extendability, rechargeability ExB van der Waals Fe3 GeTe2...
Abstract Thermometry is essential in laboratory and industry settings. We propose a noninvasive temperature measurement method based on the superparamagnetic properties of nickel-plated films. When nickel (Ni) film uniformly heated from 100 K to 300 K, we observe that polarization angle reflected polarized light decreases correspondingly. Compared with optical measurement, this introduces magnetic physical quantity, which increases penetration measurement. greatly amount information...
Element substitution of BaTiO3-based compounds has been demonstrated as a powerful way for designing novel electronic materials (such polar metals and multiferroics). To trigger magnetism into ferroelectric BaTiO3, general substituted elements are magnetic transition Mn, Fe, Co). The doping effect rare-earth Dy) in was barely investigated. Here, we report the coexistence electric polarization epitaxial Dy0.5Ba0.5TiO3 films. single-crystalline films were synthesized by high-pressure magnetron...
Interfacial coupling is one of the keys to manipulating magnetic/nonmagnetic two-dimensional (2D) heterostructures for novel functionalities. The MnPSe
The spin-orbit assisted Mott insulator $α$-RuCl$_3$ is a prime candidate for material realization of the Kitaev quantum spin liquid. While little attention has been paid to charge degrees freedom, effects, such as electric polarization, may arise in this system, which could possibly allow electrical access low-energy excitations liquids. Here, we demonstrate ferroelectricity $α$-RuCl$_3$, by means pyroelectric, second harmonic generation and specific heat measurements. polarization signal...
