Local Symmetry Breaking in Skyrmion-Hosting Centrosymmetric Hexagonal Compounds
Anupam K. Singh, Krishna K. Dubey, Parul Devi +10
Dzyaloshinskii-Moriya interaction (DMI) plays a crucial role in stabilizing the exotic topologically stable skyrmion spin textures in the noncentrosymmetric crystals. The recent di…
Evidence for Emergent Kagome Spin Configuration with Concomitant Transverse and Longitudinal Spin-Glass Freezing in the Chemically Ordered M-type Hexaferrite BaFe12O19
Keshav Kumar, Anatoliy Senyshyn, Dhananjai Pandey
Frustration effects in magnetic systems have traditionally been investigated considering pre-existing site-disorder or lattice geometry of the high-temperature paramagnetic phase.…
Sr3CrN3: a new electride with partially filled d-shells
Padtaraporn Chanhom, Kevin E. Fritz, Lee Burton +8
Electrides are ionic crystals in which the electrons prefer to occupy free space, serving as anions. Because the electrons prefer to be in the pockets, channels, or layers to the a…
A structural perspective on the origin of the anomalous weak-field piezoelectric response at the polymorphic phase boundaries of (Ba, Ca)(Ti, M)O3 lead-free piezoelectrics
Mulualem Abebe, Kumar Brajesh, Anupam Mishra +2
In this paper, we compare the structural features of Ca modified Ba(Ti, Sn)O3 with that of its Ca-free counterpart to understand why the Ca-modified variant of this lead-free piezo…
Superionic diffusion through frustrated energy landscape
D. Di Stefano, A. Miglio, K. Robeyns +12
Solid-state materials with high ionic conduction are necessary to many technologies including all-solid-state Li-ion batteries. Understanding how crystal structure dictates ionic d…
Space group symmetries of the phases of (Pb0.94Sr0.06)(ZrxTi1-x)O3 across the antiferrodistortive phase transition in the composition range 0.620<x<0.940
Ravindra Singh Solanki, Anatoliy Senyshyn, Dhananjai Pandey
The existing controversies about the space group symmetries of Pb(ZrxTi1-x)O3 (PZT) above and below antiferrodistortive (AFD) phase transition temperature (TAFD) in the Zr4+- rich…
Room temperature tetragonal noncollinear antiferromagnet PtMnGa
S. Singh, S. W. D'Souza, E. Suard +7
Here we present the tetragonal stoichiometric Heusler compound PtMnGa with the noncollinear AFM order stable up to 350 K. It is resolved by the neutron diffraction as a helical…
