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…
Measurement of spin dynamics in a layered nickelate using x-ray photon correlation spectroscopy: Evidence for intrinsic destabilization of incommensurate stripes at low temperatures
Alessandro Ricci, Nicola Poccia, Gaetano Campi +15
We study the temporal stability of stripe-type spin order in a layered nickelate with X-ray photon correlation spectroscopy and observe fluctuations on time scales of tens of minut…
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…
