Tunable layered-magnetism-assisted magneto-Raman effect in a two-dimensional magnet
Wencan Jin, Zhipeng Ye, Xiangpeng Luo +13
We use a combination of polarized Raman spectroscopy experiment and model magnetism-phonon coupling calculations to study the rich magneto-Raman effect in the two-dimensional (2D)…
Magnetic field-induced quantum phase transitions in a van der Waals magnet
Siwen Li, Zhipeng Ye, Xiangpeng Luo +10
Exploring new parameter regimes to realize and control novel phases of matter has been a main theme in modern condensed matter physics research. The recent discovery of 2D magnetis…
Magneto-memristive switching in a two-dimensional layer antiferromagnet
Hyun Ho Kim, Shengwei Jiang, Bowen Yang +7
Memristive devices whose resistance can be hysteretically switched by electric field or current are intensely pursued both for fundamental interest as well as potential application…
Quantum tunneling devices incorporating two-dimensional magnetic semiconductors
Hyun Ho Kim, Adam W. Tsen
Research in two-dimensional (2D) materials has experienced rapid growth in the past few years. In particular, various layered compounds exhibiting quantum phenomena, such as superc…
Tailored tunnel magnetoresistance response in three ultrathin chromium trihalides
Hyun Ho Kim, Bowen Yang, Shangjie Tian +4
Materials that demonstrate large magnetoresistance have attracted significant interest for many decades. Recently, extremely large tunnel magnetoresistance (TMR) has been reported…
Evolution of interlayer and intralayer magnetism in three atomically thin chromium trihalides
Hyun Ho Kim, Bowen Yang, Siwen Li +16
We conduct a comprehensive study of three different magnetic semiconductors, CrI, CrBr, and CrCl, by incorporating both few- and bi-layer samples in van der Waals tunne…
One million percent tunnel magnetoresistance in a magnetic van der Waals heterostructure
Hyun Ho Kim, Bowen Yang, Tarun Patel +5
We report the observation of a very large negative magnetoresistance effect in a van der Waals tunnel junction incorporating a thin magnetic semiconductor, CrI3, as the active laye…
Dimensionality-driven orthorhombic MoTe2 at room temperature
Rui He, Shazhou Zhong, Hyun Ho Kim +9
We use a combination of Raman spectroscopy and transport measurements to study thin flakes of the type-II Weyl semimetal candidate MoTe2 protected from oxidation. In contrast to bu…
