Doping-induced Ferromagnetic order and its unusual evolution to Helical Antiferromagnetic Order in Sr(Ni $_{1 - x}$ Co $_{x}$ ) $_{2}$ P $_{2}$

A. Sapkota, J. Schmidt, J. M. Wilde +6

SrNi $_{2}$ P $_{2}$ represents a unique case of a collapsed structural phase (one-third collapsed, where one out of every three P-P pairs forms a bond) in the A(TM) $_{2}$ X $_{2}$ family of co…

Competing magnetic phases and itinerant magnetic frustration in SrCo $_{2}$ As $_{2}$

Bing Li, B. G. Ueland, W. T. Jayasekara +9

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…

Antiferromagnetic Stacking of Ferromagnetic Layers and Doping Controlled Phase Competition in Ca $_{1 - x}$ Sr $_{x}$ Co $_{2 - y}$ As $_{2}$

Bing Li, Y. Sizyuk, N. S. Sangeetha +9

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

Spin dynamics near a putative antiferromagnetic quantum critical point in Cu substituted BaFe $_{2}$ As $_{2}$ and its relation to high-temperature superconductivity

M. G. Kim, M. Wang, G. S. Tucker +15

We present the results of elastic and inelastic neutron scattering measurements on non-superconducting Ba(Fe $_{0.957}$ Cu $_{0.043}$ ) $_{2}$ As $_{2}$ , a composition close to a quan…

Checkerboard to Stripe Charge Ordering Transition in TbBaFe2O5

D. K. Pratt, S. Chang, W. Tain +6

A combined neutron and x-ray diffraction study of TbBaFe2O5 reveals a rare checkerboard to charge ordering transition. TbBaFe2O5 is a mixed valent compound where Fe2+/Fe3+ ions are…
