Magnetocrystalline anisotropy is essential in the physics of antiferromagnets and commonly treated as a constant, not depending on an external magnetic field. However, we demonstrate that in CoO the anisotropy should necessarily depend on the magnetic field, which is shown by the spin Hall ...
high-field facilityThe AF-SF and AF-P phase boundaries of FeF 2 were measured using the Osaka high-field facility. The AF stability limit exhibits little temperature dependence before terminating at the bicritical point ( H B = 483 kOe; T B ≈ 55 K). This result strongly disagrees with ...
We studied field and temperature-driven magnetic reversal of epitaxial spin-flop coupled Fe/MnPd bilayers. The onset temperatures for the spin-flop coupling, the loop shift, and the reversal asymmetry were found to be different for the same sample, indicating their sensitivity to different interface...
An experimental study of the temperature and field dependent susceptibility of a chromium phosphinate polymer reveals a spin-flopped-like state at high field and low temperature, but above the three-dimensional ordering transition. A calculation based on the classical Heisenberg chain including anisotropy...
The spin-flop field H c and the direction of the flopped spins has been determined. AC Botterman,WJMD Jonge,PD Leeuw - 《Physics Letters A》 被引量: 1发表: 1969年 Spin-Flopping in MnF 2 MnF 2 by High Magnetic Fields The magnetization of CsMnCl 3·2H 2O has been measured up to ...
This latter quantity presents a suddenvariation as the spin-flop to paramagnet phase transition line is crossed. Thiseffect could be used as a possible source of large magneto-resistance. Ourfindings may have some relevance for doped La_{2-\\delta}Sr_{\\delta}CuO_4 in amagnetic field....
When applying a magnetic field perpendicular to the surface (Bz) from −1.5 to 3.0 T, the bound state shifts linearly to a lower energy with increasing Bz, which is attributed to the Zeeman effect. Remarkably, when applying a large range of Bz from −8.0 to 8.0 T, the magnetic field...
Mean-field theory and renormalization-group arguments are used to study the phase diagram of an anisotropic n-component d-dimensional magnetic system with a uniaxially random magnetic field. The resulting phase diagram is shown to be very similar to that of anisotropic antiferromagnets in a uniform...
Magnetization measurements were made for the diluted antiferromagnet MnxMg1−xTiO3 up to high-field region. The critical field of the spin-flop-like transition HSF approaches zero at x ∼ 0.6 and the magnetization curve becomes not to depend on directions of the applied field indicating that...
However, above a certain temperature the coercivity changes sign and there are additional high field transitions. This crossover temperature, T CO , depends on the composition of the multilayers. In sufficiently high fields, perpendicular to the multilayerfilm plane, the energy is minimized by an ...
