Published in 2024 at "Annalen der Physik"

DOI: 10.1002/andp.202400226

Abstract: The manipulation of the electron spin direction at very low electron energies is demonstrated by exploiting the exchange field present within a magnetic thin film. The design of the lab‐on‐chip integrated magnetic tunnel transistor allows… read more here.

Published in 2025 at "RSC Advances"

DOI: 10.1039/d5ra03472h

Abstract: The Gibbs free energy of spin transitions in the heptanuclear models of 1D Fe(ii) spin crossover 1,2,4-triazole complexes has been estimated using DFT methods. The complexes modelled were [Fe(Htrz)2trz]BF4 (Htrz = 4H-1,2,4-triazole, trz = 1,2,4-triazolato),… read more here.

Published in 2024 at "Chinese Physics Letters"

DOI: 10.1088/0256-307x/41/6/067401

Abstract: Antiferromagnetic spin fluctuation is regarded as the leading driving force for electron pairing in high-Tc superconductors. In iron-based superconductors, spin excitations at low energy range, especially the spin-resonance mode at ER ∼ 5kBTc, are important… read more here.

Published in 2024 at "Physical Review B"

DOI: 10.1103/physrevb.112.024420

Abstract: Magnonic black holes-analogue event horizons for the spin-wave collective excitations of ordered magnets-can be used for fundamental research, for example for investigating Hawking radiation, but also for technological applications of spin waves. Here we show… read more here.

Published in 2019 at "Physical review letters"

DOI: 10.1103/physrevlett.122.137201

Abstract: dc-magnetization data measured down to 40 mK speak against conventional freezing and reinstate YbMgGaO_{4} as a triangular spin-liquid candidate. Magnetic susceptibility measured parallel and perpendicular to the c axis reaches constant values below 0.1 and 0.2 K,… read more here.

Published in 2018 at "European Physical Journal B"

DOI: 10.1140/epjb/e2018-90519-4

Abstract: We study the energy and spin relaxations in drift transport of electrons in n -doped GaAs. Stating from the rate of change of phonon occupancy in a relaxation time approximation and the electronic power dissipated… read more here.
