Design of magnetic spirals in layered perovskites: Extending the stability range far beyond room temperature

In insulating materials with ordered magnetic spiral phases, ferroelectricity can emerge owing to the breaking of inversion symmetry. This property is of both fundamental and practical interest, particularly with a view to exploiting it in low-power electr ...

Negative-pressure-induced helimagnetism in ferromagnetic cubic perovskites Sr1-xBaxCoO3

Henrik Moodysson Rønnow, Jonathan White

Helimagnetic materials are identified as promising for novel spintronic applications. Since helical spin order is manifested as a compromise of competing magnetic exchange interactions, its emergence is limited by unique constraints imposed by the crystall ...

Disordered skyrmion phase stabilized by magnetic frustration in a chiral magnet

Henrik Moodysson Rønnow, Jonathan White

Magnetic skyrmions are vortex-like topological spin textures often observed to form a triangular-lattice skyrmion crystal in structurally chiral magnets with the Dzyaloshinskii-Moriya interaction. Recently, beta-Mn structure-type Co-Zn-Mn alloys were ident ...

Magnetic properties of surface-adsorbed single rare earth atoms, molecules, and atomic scale clusters

Aparajita Singha

This thesis presents combined experimental and theoretical investigations of nanoscale, surface-supported magnets based on rare earths (RE) to understand and control the magnetic properties down to the scale of single atoms. We present the effects of adato ...

Building Composite Iron-Manganese Oxide Flowerlike Nanostructures: A Detailed Magnetic Study

Davide Deiana

Here we show that it is possible to produce different magnetic core multiple shell heterostructures from monodisperse Fe3O4 spherical magnetic seeds by finely controlling the amount of a manganese precursor and using, in a smart and simple way, a cation-ex ...

High-Temperature Ferrimagnetism with Large Coercivity and Exchange Bias in the Partially Ordered 3d/5d Hexagonal Perovskite Ba2Fe1.12Os0.88O6

Philip Pattison

Double perovskite oxides A(2)BB'O-6 combining 3d and 4d or 5d transition metal ions at the B and B' sites feature a variety of magnetic and magneto-electric properties. Targeting Ba2FeOsO6, we synthesized powder samples of nonstoichiometric Ba2Fe1.12Os0.88 ...

J1-J2 square lattice antiferromagnetism in the orbitally quenched insulator MoOPO4

László Forró, Henrik Moodysson Rønnow, Arnaud Magrez, Oleg Yazyev, Ivica Zivkovic, Helmuth Berger, Bálint Náfrádi, Lin Yang, Peter Babkevich, Noore Elahi Shaik

We report magnetic and thermodynamic properties of a 4d1 (Mo5+) magnetic insulator MoOPO4 single crystal, which realizes a J1−J2 Heisenberg spin-1/2 model on a stacked square lattice. The specific-heat measurements show a magnetic transition at 16 K which ...

Magnetic properties of CeAlSi and CeAlGe

Lorenzo Berardo

This TPIV experiment deals with first measurements of CeAlSi and CeAlGe magnetic properties and allows to a comparison between these last two. The first step is a description of MPMS measurement, then the paramagnetism and ferromagnetism theory leads to an ...
