Shape memory materials are capable of returning to their original form post-deformation, but those with high actuation performances remain scarce. Here the authors reveal that CaFe2As2 exhibits cryogenic linear shape memory behaviour with high recove

We report the magnetic ordering and structural distortion in PrFeAsO crystals, the basis compound for one of the oxypnictide superconductors, using high-resolution x-ray diffraction, neutron diffraction, and x-ray resonant magnetic scattering (XRMS).

The magnetic structure of Nd in NdFeAsO compound has been investigated by x-ray resonant magnetic scattering at the Nd ${L}_{2}$ edge ($E=6.725$ keV) at $1.7\ensuremath{\le}T\ensuremath{\le}15$ K. At $T=1.7$ K we find that the Nd moments are aligned

We report on the results of a high-energy x-ray diffraction study of Al–Pd–Mn to investigate the solidification products obtained during free-cooling using an electrostatic levitation furnace. The primary solidification product from the melt is i

Whereas magnetic frustration is typically associated with local-moment magnets in special geometric arrangements, here we show that SrCo$_{2}$As$_{2}$ is a candidate for frustrated itinerant magnetism. Using inelastic neutron scattering (INS), we fin

In search of a quantum phase transition between the two-dimensional ($2\mathrm{D}$) ferromagnetism of ${\mathrm{CaCo}}_{2\ensuremath{-}y}{\mathrm{As}}_{2}$ and stripe-type antiferromagnetism in ${\mathrm{SrCo}}_{2}{\mathrm{As}}_{2}$, we instead find

We report on the crystal and magnetic structures, magnetic, and transport properties of SrMnSb$_2$ single crystals grown by the self-flux method. Magnetic susceptibility measurements reveal an antiferromagnetic (AFM) transition at $T_{\rm N} = 295(3)
