Evidence for Conical Magnetic Structure in M-type BaFe12O19 Hexaferrite: A Combined Single-Crystal XMCD and Neutron Diffraction Study
Keshav Kumar, Shrawan K. Mishra, Sanjay Singh +5
The magnetic ground state of BaFe12O19 (BFO) was investigated using X-ray absorption at 1.2 K and 1.5 K, respectively. The XMCD measurements on single-crystals of BFO in grazing in…

Evidence for coexistence of spin-glass and ferrimagnetic phases in BaFe12O19 due to basal plane freezing
Keshav Kumar, Shrawan Kumar Mishra, Ivan Baev +2
We present here the results of low-temperature magnetization and X-ray magnetic circular dichroism studies on single crystals of BaFe12O19 which reveal for the first time the emerg…

Direct Visualization of Spatial inhomogeneity of Spin Stripes Order in La1.72Sr0.28NiO4
Gaetano Campi, Nicola Poccia, Boby Joseph +14
In several strongly correlated electron systems, defects, charge and local lattice distortions are found to show complex inhomogeneous spatial distributions. There is growing evide…
