EuCo2P2: A Model Molecular-Field Helical Heisenberg Antiferromagnet
N. S. Sangeetha, Abhishek Pandey, D. C. Johnston
The Eu spins-7/2 in EuCo2P2 with the tetragonal ThCr2Si2-type structure have the prototypical noncollinear helical antiferromagnetic structure below the Neel temperature TN = 66.5…
Pressure-induced collapsed-tetragonal phase in SrCo2As2
W. T. Jayasekara, U. S. Kaluarachchi, B. G. Ueland +16
We present high-energy x-ray diffraction data under applied pressures up to p = 29 GPa, neutron diffraction measurements up to p = 1.1 GPa, and electrical resistance measurements u…
Ba{0.4}Rb{0.6}Mn2As2: A Prototype Half-Metallic Ferromagnet
Abhishek Pandey, D. C. Johnston
Half-metallic ferromagnetism (FM) in single-crystal Ba{0.39(1)}Rb{0.61(1)}Mn2As2 below its Curie temperature TC = 103(2) K is reported. The magnetization M versus applied magnetic…
Coexistence of antiferromagnetic and ferromagnetic spin correlations in SrCo2As2 revealed by 59Co and 75As NMR
P. Wiecki, V. Ogloblichev, Abhishek Pandey +2
In nonsuperconducting, metallic paramagnetic SrCo2As2, inelastic neutron scattering measurements have revealed strong stripe-type (q) = (,0) antiferromagnetic (AFM) spin corr…
Itinerant ferromagnetism in the As 4 conduction band of BaKMnAs identified by x-ray magnetic circular dichroism
B. G. Ueland, Abhishek Pandey, Y. Lee +9
X-ray magnetic circular dichroism (XMCD) measurements on single-crystal and powder samples of BaKMnAs show that the ferromagnetism below $T_{\textrm{C}}…
