Inducing Magnetic Phase Transitions in Monolayer CrI3 via Lattice Deformations

Oleg Yazyev, Michele Pizzochero

Atomically thin films of layered chromium triiodide (CrI3) have recently been regarded as suitable candidates for a wide spectrum of technologically relevant applications, mainly owing to the opportunities they offer for achieving a reversible transition b ...

Probing magnetism in atomically thin semiconducting PtSe2

Andras Kis, Oleg Yazyev, Ahmet Avsar, Michele Pizzochero, Alberto Ciarrocchi, Mukesh Kumar Tripathi, Cheol Yeon Cheon

Atomic-scale disorder in two-dimensional transition metal dichalcogenides is often accompanied by local magnetic moments, which can conceivably induce long-range magnetic ordering into intrinsically non-magnetic materials. Here, we demonstrate the signatur ...

Antiferromagnetic resonance in TmFeO3 at high temperatures

Jean-Philippe Ansermet, Arnaud Magrez, Haiming Yu, Marcin Bialek

Temperature dependence of the antiferromagnetic resonance spectrum in a thulium orthoferrite (TmFeO3) poly-crystalline sample was studied by transmission spectroscopy in the frequency range of 0.1–0.75 THz and temperature range of 300–670 K, up to its Néel ...

Giant anomalous Hall effect in quasi-two-dimensional layered antiferromagnet Co1/3NbS2

László Forró, Helmuth Berger, Edoardo Martino

The discovery of the anomalous Hall effect (AHE) in bulk metallic antiferromagnets (AFMs) motivates the search of the same phenomenon in two-dimensional (2D) systems, where a quantized anomalous Hall conductance can, in principle, be observed. Here we pres ...

Structural characterization and magnetic properties of chromium jarosite KCr3(OD)(6)(SO4)(2)

Sofie Janas

Potassium chromium jarosite, KCr3(OH)(6)(SO4)(2) (Cr-jarosite), is considered a promising candidate to display spin liquid behavior due to the strong magnetic frustration imposed by the crystal structure. However, the ground state magnetic properties have ...
