Self-induced thermo-optical effects in silicon and germanium dielectric nanoresonators

Dielectric nanoresona tors uniquely support both magnetic and electric resonances across a wide wavelength range. They are thus being exploited in a growing number of groundbreaking applications. In particular, they have been recently suggested as promisin ...

Low-temperature monoclinic layer stacking in atomically thin CrI3 crystals

Marco Gibertini, Zhe Wang

Chromium triiodide, CrI3, is emerging as a promising magnetic two-dimensional semiconductor where spins are ferromagnetically aligned within a single layer. Potential applications in spintronics arise from an antiferromagnetic ordering between adjacent lay ...

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 ...

Exchange Interactions Mediated by Nonmagnetic Cations in Double Perovskites

Henrik Moodysson Rønnow, Oleg Yazyev, Peter Babkevich, Vamshi Mohan Katukuri, Sami Juhani Vasala

Establishing the physical mechanism governing exchange interactions is fundamental for exploring exotic phases such as quantum spin liquids in real materials. In this Letter, we address exchange interactions in Sr2CuTexW1-xO6, a series of double perovskite ...

Reversible Magnetic Transition in a Bench-Stable Radical Cation Triggered by Structural Transition in the Magnetically Silent Counteranion

Sergio Vela Llausi

Fabrication of bench-stable radical ions under ambient conditions is of utmost significance from the perspective of materials and structural (solid-state) chemistry. Two exceptionally stable benzotriazinyl radical cationic salts of 1-phenyl-3(phenylamino)- ...

Resonant inelastic X-ray scattering of magnetic excitations under pressure

Matteo Rossi

Resonant inelastic X-ray scattering (RIXS) is an extremely valuable tool for the study of elementary, including magnetic, excitations in matter. The latest developments of this technique have mostly been aimed at improving the energy resolution and perform ...

Frustration and Randomness

Péter Szirmai

Spin systems with strong magnetic interactions might remain disordered avoiding conventional magnetic long-range ordering due to zero-point quantum fluctuations, and supporting a Quantum Spin Liquid (QSL) state. Long-range quantum entanglement in QSLs prom ...

Raman Characterization of the Charge Density Wave Phase of 1T-TiSe2: From Bulk to Atomically Thin Layers

Klaus Kern, Marko Burghard, Alexander Ronald Hoyer

Raman scattering is a powerful tool for investigating the vibrational properties of two-dimensional materials. Unlike the 2H phase of many transition metal dichalcogenides, the 1T phase of TiSe2 features a Raman-active shearing and breathing mode, both of ...
