Spontaneous topological Hall effect induced by non-coplanar antiferromagnetic order in intercalated van der Waals materials
H. Takagi, R. Takagi, S. Minami +14
In ferromagnets, electric current generally induces transverse Hall voltage in proportion to magnetization (anomalous Hall effect), and it is frequently used for electrical readout…
Spin wave stiffness and damping in a frustrated chiral helimagnet CoZnMn as measured by small-angle neutron scattering
V. Ukleev, K. A. Pschenichnyi, O. Utesov +7
Multiple intriguing low temperature phenomena have recently been discovered in the family of chiral cubic Co-Zn-Mn compounds with Mn-type structure. In particular, CoZn…
Enhancement of superconductivity and its relation to lattice expansion in InTe
M. Kriener, M. S. Bahramy, Y. Tokura +1
The quest to govern the driving forces behind superconductivity and gain control over the superconducting transition temperature is as old as the phenomenon itself. Microsc…
Refining magnetic interactions from the magnetic field dependence of spin-wave excitations in magnetoelectric LiFePO
L. Peedu, V. Kocsis, D. Szaller +13
We investigated the spin excitations of magnetoelectric by THz absorption spectroscopy in magnetic fields up to 33T. By studying their selection rules, we fou…
Terahertz lattice and charge dynamics in ferroelectric semiconductor SnPbTe
Y. Okamura, H. Handa, R. Yoshimi +5
The symmetry breaking induced by the ferroelectric transition often triggers the emergence of topological electronic states such as Weyl fermions in ferroelectric-like metals/semim…
Real-space observation of emergent complexity of phase evolution in micrometer-sized IrTe crystals
H. Oike, K. Takeda, M. Kamitani +2
We report complex behaviors in the phase evolution of transition-metal dichalcogenide IrTe thin flakes, captured with real-space observations using scanning Raman microscopy. T…
Field-induced multiple metal-insulator crossovers of correlated Dirac electrons of perovskite CaIrO
R. Yamada, J. Fujioka, M. Kawamura +10
The interplay between electron correlation and topology of relativistic electrons may lead to a new stage of the research on quantum materials and emergent functions. The emergence…
In-situ electric field control of THz non-reciprocal directional dichroism in the multiferroic BaCoGeO
J. Vít, J. Viirok, L. Peedu +11
Non-reciprocal directional dichroism, also called the optical-diode effect, is an appealing functional property inherent to the large class of non-centrosymmetric magnets. However,…
Charge-cluster glass in an organic conductor
F. Kagawa, T. Sato, K. Miyagawa +5
Geometrically frustrated spin systems often do not exhibit long-range ordering, resulting in either quantum-mechanically disordered states, such as quantum spin liquids, or classic…
