High‐Entropy Magnetism of Murunskite

Henrik Moodysson Rønnow, Ivica Zivkovic, Thomas La Grange, Davor Tolj, Rongrong Cai

Murunskite (K 2 FeCu 3 S 4 ) bridges the two known families of high‐temperature superconductors, cuprates and iron‐pnictides, structurally and electronically. Like these families, murunskite exhibits an antiferromagnetic (AF)‐like response with an ordered ...

Investigating domain structures and superdomains in ferroelectric PbTiO3 based heterostructures on DyScO3

Duncan Thomas Lindsay Alexander, Pau Torruella Besa

This work focuses on the complex ferroelastic/ferroelectric domain structure in the prototypical ferroelectric PbTiO3 epitaxially strained on (110)o-oriented DyScO3 substrates, with a 22 nm-thick bottom SrRuO3 electrode. High quality epitaxial growth has b ...

Magnon gap excitations in van der Waals antiferromagnet MnPSe3

Jean-Philippe Ansermet

Magneto-spectroscopy methods have been employed to study the zero-wavevector magnon excitations in MnPSe3. Experiments carried out as a function of temperature and the applied magnetic field show that two low-energy magnon branches of MnPSe3 in its antifer ...

Multiphase magnetism in Yb2Ti2O7

Gregory Scott Tucker

We use neutron scattering to show that ferromagnetism and antiferromagnetism coexist in the low T state of the pyrochlore quantum magnet Yb2Ti2O7. While magnetic Bragg peaks evidence long-range static ferromagnetic order, inelastic scattering shows that sh ...

Light induced electron spin resonance properties of van der Waals CrX3 (X = Cl, I) crystals

Oleg Yazyev, Michele Pizzochero, Ravi Yadav

The research on layered van der Waals (vdW) magnets is rapidly progressing owing to exciting fundamental science and potential applications. In bulk crystal form, CrCl3 is a vdW antiferromagnet with in-plane ferromagnetic ordering below 17K, and CrI3 is a ...

Quantum phase transitions beyond Landau-Ginzburg theory in one-dimensional space revisited

Christopher Marc Mudry

The phase diagram of the quantum spin-1/2 antiferromagnetic J(1)-J(2) XXZ chain was obtained by Haldane using bosonization techniques [Haldane, Phys. Rev. B 25, 4925 (1982); 26, 5257 (1982)]. It supports three distinct phases for 0

Spin Excitations in a 4f-3d Heterodimer on MgO

Harald Brune, François Patthey, Fabio Donati, Christian Wäckerlin, Aparajita Singha, Donat Fabian Natterer

We report on the magnetic properties of HoCo dimers as a model system for the smallest intermetallic compound of a lanthanide and a transition metal atom. The dimers are adsorbed on ultrathin MgO(100) films grown on Ag(100). New for 4f elements, we detect ...

Nodeless superconductivity in the noncentrosymmetric Mo3Rh2N superconductor: A mu SR study

Joël Mesot

The noncentrosymmetric superconductor Mo3Rh2N, with T-c = 4.6 K, adopts a beta-Mn-type structure (space group P4(1)32), similar to that of Mo3Al2C. Its bulk superconductivity was characterized by magnetization and heat-capacity measurements, while its micr ...

Uniaxial 2D Superlattice of Fe-4 Molecular Magnets on Graphene

Harald Brune, Stefano Rusponi, Luca Gragnaniello

We demonstrate that electrospray deposition enables the fabrication of highly periodic self-assembled arrays of Fe4H single molecule magnets on graphene/Ir(111). The energetic positions of molecular states are probed by means of scanning tunneling spectros ...

Broadband Dielectric Response in Hard and Soft PZT : Understanding Softening and Hardening Mechanisms

Li Jin

Lead zirconate titanate (Pb(Zr1-xTix)O3 or PZT) ferroelectric ceramics have been widely used in transducers, actuators, and sensors, since they posses high dielectric and piezoelectric properties with a relatively high temperature of operation. Commerciall ...

X-ray ferromagnetic resonance spectroscopy

Harald Brune, Giovanni Boero, Radivoje Popovic, Stefano Rusponi, Pietro Gambardella

We present a method to measure continuous-wave ferromagnetic resonance (FMR) spectra based on the core-level absorption of circularly polarized x rays. The technique is demonstrated by using a monochromatic x-ray beam incident on an yttrium-iron-garnet sam ...
