Magnetic correlations in subsystems of the misfit [CaCoO][CoO] cobaltate

Abdul Ahad, K. Gautam, K. Dey +7

[CaCoO][CoO], a two dimensional misfit metallic compound, is famous for its rich phases accessed by temperature, high temperature spin-state transition,…

Colossal pressure-induced softening in scandium fluoride

Zhongsheng Wei, Lei Tan, Guanqun Cai +4

The counter-intuitive phenomenon of pressure-induced softening in materials is likely to be caused by the same dynamical behaviour that produces negative thermal expansion. Through…

Strengthening the magnetic interactions in pseudobinary first-row transition metal thiocyanates, (NCS)

Euan N. Bassey, Joseph A. M. Paddison, Evan N. Keyzer +6

Understanding the effect of chemical composition on the strength of magnetic interactions is key to the design of magnets with stronger exchange interactions. The magnetic divalent…

Evidence of a cluster spin-glass state in the B-site disordered perovskite SrTi0.5Mn0.5O3

Shivani Sharma, Poonam Yadav, Tusita Sau +5

SrTi0.5Mn0.5O3 (STMO) is a chemically disordered perovskite having random distribution of Ti and Mn over 1b site. Striking discrepancies about the structural and magnetic propertie…

MuSR and neutron diffraction studies on the tuning of spin-glass phase in partially ordered double perovskite SrMnWO

Poonam Yadav, Shivani Sharma, Peter J. Baker +3

Tunability of the partially ordered double perovskite (PODP) and coexisting spin-glass phase in SrMn1-xWxO3 (x=0.20 to 0.40) have been studied using neutron powder diffraction (NPD…

Evidence for ground state and defect-induced spin glass behaviour in the pyrochlore osmate YOsO

N. R. Davies, C. V. Topping, H. Jacobsen +14

We present AC and DC magnetometry, heat capacity, muon spin relaxation (SR) and resonant inelastic X-ray scattering (RIXS) studies of the pyrochlore osmate YOsO. We…
