Spin Textures in 2D Magnets

The continuous reduction of the structural size in nanotechnology slowed down over the last decade, approaching the natural limit of single atoms as building blocks of matter. Therefore, intensive research is directed toward exploring new frontiers, in par ...

Magneto-optical study of metamagnetic transitions in the antiferromagnetic phase of alpha-RuCl3

Zhe Wang

alpha-RuCl3 is a promising candidate material to realize the so far elusive quantum spin liquid ground state. However, at low temperatures, the coexistence of different exchange interactions couple the effective pseudospins into an antiferromagnetically zi ...

Canted antiferromagnetic phases in the candidate layered Weyl material EuMnSb2

Xiao Wang

EuMnSb2 is a candidate topological material which can be tuned towards a Weyl semimetal, but there are differing reports for its antiferromagnetic (AFM) phases. The coupling of bands dominated by pure Sb layers hosting topological fermions to Mn and Eu mag ...

Vital role of magnetocrystalline anisotropy in cubic chiral skyrmion hosts

Henrik Moodysson Rønnow, Jonathan White

Magnetic anisotropy is anticipated to govern the formation of exotic spin textures reported recently in cubic chiral magnets, like low-temperature tilted conical and skyrmion lattice (SkL) states and metastable SkLs with various lattice geometry. Motivated ...

Controlling magnetic order, magnetic anisotropy, and band topology in the semimetals Sr(Mn0.9Cu0.1)Sb-2 and Sr(Mn0.9Zn0.1)Sb-2

Yong Liu

Neutron diffraction and magnetic susceptibility studies show that orthorhombic single-crystals of topological semimetals Sr(Mn0.9Cu0.1)Sb-2 and Sr(Mn0.9Zn0.1)Sb-2 undergo three-dimensional C-type antiferromagnetic (AFM) ordering of the Mn2+ moments at T-N ...

The adaptive interpolation method for proving replica formulas. Applications to the Curie-Weiss and Wigner spike models

Nicolas Macris, Jean François Emmanuel Barbier

In this contribution we give a pedagogic introduction to the newly introduced adaptive interpolation method to prove in a simple and unified way replica formulas for Bayesian optimal inference problems. Many aspects of this method can already be explained ...

Thermodynamic evidence of a second skyrmion lattice phase and tilted conical phase in Cu2OSeO3

Helmuth Berger

Precision measurements of the magnetization and ac susceptibility of Cu2OSeO3 are reported for magnetic fields along different crystallographic directions, focusing on the border between the conical and the field-polarized state for a magnetic field along ...

Magnetic exchange parameters and anisotropy of the quasi-two-dimensional antiferromagnet NiPS3

Diane Virginie Marie Lançon

Neutron inelastic scattering has been used to measure the magnetic excitations in powdered NiPS3, a quasitwo-dimensional antiferromagnet with spin S = 1 on a honeycomb lattice. The spectra show clear, dispersive magnons with a similar to 7 meV gap at the B ...

Magnetic phase diagram of Ca-substituted EuFe2As2

The simultaneous presence of an Fe-related spin-density wave and the antiferromagnetic order of Eu-2(+) moments ranks EuFe2As2 among the most interesting parent compounds of iron-based pnictide superconductors. Here we explore the consequences of the dilut ...
