January 2017 - Welcome to Dr Ales Stefancic and Marta Crisanti
We welcome Dr Ales Stefancic who has recently joined the Group as Post-Doctoral Research Assistant (PDRA) studying the physics of Skyrmionic materials. Ales will work here at Warwick as part of a larger EPSRC Programme Grant Skyrmionics: From Magnetic Excitations to Functioning Low-Energy Devices involving the Universities of Durham, Cambridge, Southampton, and Oxford. The work here at Warwick will be led by Prof. Geetha Balakrishnan.
We also welcome Marta Crisanti who joins us as a Warwick/ILL Ph.D. student working under the joint supervision of Don Paul (Warwick) and Robert Cubitt who works in the Large Scale Structures Group at the ILL. Marta will also be working on Skyrmionic materials, focussing on the use of small angle neutron scattering.
Oxides containing 5d ions, particularly Ir4+, offer possibilities for interesting spin-orbit and spin-lattice coupling effects. In these materials, the energy scales for spin-orbit interactions, Coulomb repulsion, and crystalline-electric fields can be very similar. Competition between these three energies can result in exotic magnetic states such as spin-orbit entanglement, extreme magnetic exchange anisotropy leading to, for example, a Kitaev spin liquid, and spin-orbit entangled Mott insulating behaviour.
Using experiments performed at the National High Magnetic Field Laboratory, a team from the USA, UK and South Korea (including Paul Goddard at Warwick) have observed extremely large coercive magnetic fields of up to 55 T in Sr3NiIrO6 and 52 T in Sr3CoIrO6, with switched magnetic moments of ≈ 1μB and 3μB per formula unit, respectively. Rather than the switching of magnetic domains, which is the cause of the coercive fields of traditional ferromagnets, the large hysteresis observed in our materials evolves out of a frustrated, antiferromagnetic ground state that incorporates an entangled spin-orbit state on the 5d ion.

A paper has been published in Nature Physics that reveals that magnetic fragmentation occurs in the spin ice candidate Nd2Zr2O7. The work was carried out in collaboration with colleagues from the CEA in Saclay and the ILL, CEA, and the Institut Neel in Grenoble.
It has recently been suggested that in spin ice, the magnetic moment field can fragment, resulting in a dual ground state consisting of a fluctuating spin liquid, a so-called Coulomb phase, on top of a magnetic monopole crystal. Here we show, by means of neutron scattering measurements, that such fragmentation occurs in Nd2Zr2O7. We observe the spectacular coexistence of an antiferromagnetic order induced by the monopole crystallization and a fluctuating state with ferromagnetic correlations.
Experimentally, this fragmentation manifests itself through the superposition of magnetic Bragg peaks, characteristic of the ordered phase, and a pinch point pattern, characteristic of the Coulomb phase. These results highlight the relevance of the fragmentation concept to describe the physics of systems that are simultaneously ordered and fluctuating.

|A paper has been published in Nature Physics that studies the interaction between mononpoles in spin ice. The work was carried out in collaboration with colleagues at UCL - London, Institut Neel - Grenoble, Cardiff and Oxford Universities, and KIT - Japan. Thermal quenches in spin ice are used to prepare metastable populations of bound pairs of positive and negative emergent magnetic monopoles at millikelvin temperatures. The application of a magnetic field results in a universal exponential-root field growth of magnetic current, thus confirming the microscopic Coulomb force between the magnetic monopole quasiparticles and establishing a magnetic analogue of the Poole–Frenkel effect.|
At temperatures above 300 mK, gradual restoration of kinetic monopole equilibria causes the non-Ohmic current to smoothly evolve into the high-field Wien effect for magnetic monopoles, as confirmed by comparison to a recent and rigorous theory of the Wien effect in spin ice. The results extend the universality of the exponential-root field form into magnetism and illustrate the power of emergent particle kinetics to describe far-from-equilibrium response in complex systems.

The scope of the meeting also covered the use of oxides in applications and in industry.

Neutron scattering and magnetization measurements down to 90 mK have been used to determine the magnetic ground state of the spin-ice candidate Nd2Zr2O7. Along with colleagues from Grenoble and Saclay we show Nd2Zr2O7 undergoes a transition at 285 mK towards an all-in–all-out antiferromagnetic state, and establish the H-T phase diagram. We propose that this behaviour results from the peculiar nature of the Nd dipolar-octupolar doublet, revealing the importance of multipolar correlations in pyrochlore oxides.
