Spin-flop coupling, the interfacial perpendicular coupling between FM and AFM moments, can be utilized to control the orientation of AFM moments with the application of moderate magnetic fields on the scale of tenths of a Tesla. In this work, epitaxial bilayers of AFM La0.5Sr0.5FeO3 (LSFO)/...
The observed MR of more than 30% at lowtemperatures induced by a modest modification of the spin structure indicatesan unexpectedly strong spin-charge coupling in electron-doped cuprates.doi:10.1103/PhysRevLett.92.227003
The FM–AFM exchange coupling establishes an extra preference of magnetization alignment in Fe, where the FM spins favour perpendicular alignment with the frozen AFM spins due to the spin flop coupling between them. As the number of frozen AFM spins in CoO grows with lower T, the FM/AFM ...
Although there are N − 1 eigenstates of the Hamiltonian lying within the gap, these are purely atomic, and the symmetry of the all-to-all atom–cavity coupling prevents their excitation, rendering them completely dark. On introducing disorder, we observe the onset of a non-zero ...
Surface spin-flop transition in Fe/Cr(211) superlattices: Experiment and theory We report experimental and theoretical studies of the magnetization curves of Fe/Cr(211) superlattices with antiferromagnetic interlayer coupling and uniax... RW Wang,DL Mills,EE Fullerton,... - 《Physical Review ...
Exchange coupling between the Co and CoO layers is apparently 211u001eresponsible for the increased projection of the AFM moments perpendicular to the 211u001ecooling field. 展开 关键词:Spin Thin films Antiferromagnetism Cobalt Neel temperature Neutron diffraction 211 Cobalt oxides Exchange biasing ...
By mapping back the signal through the spin chain, the five spin frequencies and the 4 coupling frequencies are directly correlated: they are found to originate from the same branch of the network. As spins are now characterized by their connection to the chains, rather than by their individual...
While a c-axis aligned magnetic field does not alter the basic zero-field noncollinear spin structures, a field parallel to the CuO2 plane can transform the noncollinear structure to a collinear one (“spin-flop” transition), induce magnetic disorder along the c axis, and cause hysteresis ...
(2DEG), typically described asH0 == ℏ2k2/2m*whereℏis the reduced Planck’s constant,kis the wavevector, andm*is the effective mass of the electrons in the 2DEG. The termsαandβdenote the strength of the Rashba and Dresselhaus spin–orbit coupling, respectively. These terms ...
