Frustration-induced multiferroicity in hauerite MnS2
Vilmos Kocsis, Harish K. Singh, Kranthi K. Bestha +4
Pyrite-type mineral hauerite MnS is a magnetic insulator with localized moments. Below 48 K, it develops a collinear antiferromagnetic order, accompanied by unit-ce…
Robust Signatures of Fragile Topology in Nonmagnetic Materials
Viktor Könye, Ihor Nimyi, Oleg Janson +3
Some topological phases of matter are called fragile. They can be trivialized by adding additional valence bands and do not generically host protected gapless boundary states. Here…
Multipolar Piezoelectricity and Anisotropic Surface Transport in Alterelectrics
Amber Visser, Viktor Könye, Oleg Janson +3
Altermagnets are an emergent class of materials combining features of ferro- and antiferro-magnetic materials. They have spin-separated bands normally associated with ferromagnets,…
Magnetic-field tuning of the spin dynamics in the quasi-2D van der Waals antiferromagnet CuCrPS
Joyal John Abraham, Yaqian Guo, Yuliia Shemerliuk +14
The use of antiferromagnets in magnetoelectronic devices as counterparts of ferromagnets is a new, rapidly developing trend in spintronics that leverages antiferromagnetic (AFM) ma…
Fermi surface and topology of multiband superconductor BeAu
Riccardo Vocaturo, Klaus Koepernik, Dániel Varjas +3
The chiral material BeAu was recently identified as a multiband type-I superconductor with a critical temperature of 3.2 K. As a member of the B20 crystal family (space group $P2_1…

Diep Minh Nguyen, Azimjon A. Temurjonov, Daigorou Hirai +6
Low-energy spin dynamics is investigated by Cl NMR measurements in a frustrated antiferromagnet CaReOCl. The local spin susceptibility measured with the Knight…
Influence of pressure on properties of multi-gap type-I superconductor BeAu
Rustem Khasanov, Riccardo Vocaturo, Oleg Janson +7
We report on studies of the superconducting and normal state properties of the noncentrosymmetric superconductor BeAu under hydrostatic pressure conditions. The room-temperature eq…
