spin flop fieldphase boundariesFeF 2high-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)....
However, we demonstrate that in CoO the anisotropy should necessarily depend on the magnetic field, which is shown by the spin Hall magnetoresistance of the CoO|Pt device. Below the N茅el temperature CoO reveals a spin-flop transition at 240K at 7.0T, above which a hysteresis in the ...
is close to the mean-field exponent\(\beta = 0.5\), whereas in the spin-flop phase it becomes close to the critical exponent\(\beta = 0.231\)in the 2DXYspin model [48]. Hence, the spin lattice in Mn\(_2\)P\(_2\)S\(_6\)demonstrates an interesting field-driven dimensional cross...
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....
The two regions are separated by a spin-flop first-order line, by an intermediate "mixed" phase, and by a tetracritical (or bicritical) point. The exponents at this multicritical point are shown to coincide, near d=6, with those of the random-field Ising model. This phase diagram is ...
Antiferromagnetic spintronics has recently become an important research field from both a fundamental viewpoint and its strong applicative potential1,2. Antiferromagnets (AFM) have key advantages linked to their magnetic ordering: they are insensitive to perturbative external magnetic fields, stray fields ...
To this end, we fabricate a double-gate transistor based on bilayers of van der Waals antiferromagnetic semiconductor CrPSand show how a perpendicular electric displacement field can switch the spin polarization of the conduction band on and off. Because conduction band states with opposite spin ...

Magnetic-field-induced spin flop transition and magnetoelectric effect in noncentrosymmetric Ca 2 Fe 2 x Al x O 5 (0.5 ≤ x ≤ 1) single crystals have been investigated. Temperature dependence of magnetic susceptibility shows that the compounds have antiferromagnetic transition temperatures T N above...
