Metastable and localized Ising magnetism in alpha-CoV2O6 magnetization plateaus

alpha-CoV2O6 consists of j(eff) = 1/2 Ising to investigate the magnetic periodicity in the vicinity of these plateaus. We find these steps to be characterized by metastable and spatially short-range (xi similar to 10 angstrom) magnetic correlations with an ...

Coherent Epitaxial Semiconductor-Ferromagnetic Insulator InAs/EuS Interfaces: Band Alignment and Magnetic Structure

Gabriel Aeppli, Vladimir N. Strocov, Sara Marti Sanchez, Yu Liu

Hybrid semiconductor-ferromagnetic insulator heterostructures are interesting due to their tunable electronic transport, self-sustained stray field, and local proximitized magnetic exchange. In this work, we present lattice-matched hybrid epitaxy of semico ...

Magnetic dynamics across the in-field transition in Ca3Co2O6

Henrik Moodysson Rønnow, Arnaud Magrez, Ivica Zivkovic, Nagabhushan Ganesh Hegde

The discovery of multiple coexisting magnetic phases in the crystallographically homogeneous compound Ca3Co2O6 has stimulated ongoing research activity. In recent years the main focus has been on the zero-field-state properties, where exceedingly long time ...

h/e oscillations in interlayer transport of delafossites

Philip Johannes Walter Moll, Maja Deborah Bachmann, Matthias Carsten Putzke

Microstructures can be carefully designed to reveal the quantum phase of the wave-like nature of electrons in a metal. Here, we report phase-coherent oscillations of out-of-plane magnetoresistance in the layered delafossites PdCoO2 and PtCoO2. The oscillat ...

Emergence of Nontrivial Low-Energy Dirac Fermions in Antiferromagnetic EuCd2As2

Vladimir N. Strocov, Joël Mesot, Pierre Richard, Han Wang, Hang Li

Parity-time symmetry plays an essential role for the formation of Dirac states in Dirac semimetals. So far, all of the experimentally identified topologically nontrivial Dirac semimetals (DSMs) possess both parity and time reversal symmetry. The realizatio ...

Magnetic-field-induced reorientation in the spin-density-wave and the spin-stripe phases of the frustrated spin-1/2 chain compound beta-TeVO4

Helmuth Berger

beta-TeVO4 is a frustrated spin-1/2 zig-zag chain system, where spin-density-wave (SDW), vector-chiral (VC) and an exotic dynamic spin-stripe phase compete at low temperatures. Here we use torque magnetometry to study the anisotropy of these phases in magn ...

Assessing Cu2L2X4 dimeric moieties as ferromagnetic building blocks in double halide-bridged polymers (X = Cl-, Br- and L = benzamide). An experimental and computational study

Two isostructural double halide-bridged polymers, consisting of stacked Cu2L2X4 dimers, with L = benzamide (BA) and X = Cl- in CuClBA and X = Br- in CuBrBA, were synthesised. The experimental magnetic data of both compounds were recorded and it was found t ...
