A Short Review on Verwey Transition in Nanostructured Fe3O4 Materials

“…It manifests itself in a shifting (H EB ) of M-H loop along the field axis and enhancement of coercivity (H C ) when the system is cooled down in an external magnetic field through the magnetic ordering temperatures of the AFM (T N ) and FM (T C ) phases. It has been reported that the EB can be influenced by many factors in the FM/AFM system, such as the FM magnetization M FM , the thickness of FM layer t FM or AFM layer t AFM , and the anisotropy of AFM (K AFM ) or FM (K FM ) [79]. A rapid change in K FM is observed in the vicinity of T V = 120 K due to the structural transformation from cubic to a more anisotropic monoclinic phase.…”

Competition between interfacial and interlayer exchange couplings in Co/Cr2O3/Fe trilayers

“…1(c)) and 6 nm. When T > T P , the FM interlayer coupling will gradually dominate the couplings, accordingly, the step gradually disappears with increasing temperature [27]. For the FC case, the moments of FM layers and the interface of AF layers tend to the direction of external field, and the strong FM coupling in FM/AF occurs at low temperatures (see the negative exchange bias field in Fig.…”

Electronic and magnetic properties of α−FeGe2 films embedded in vertical spin valve devices

“…The magnetization reversals measured by a superconducting quantum interference device (SQUID) exhibit a clear dependence on the spacer thickness in Fe 3 Si/α-FeGe 2 /Fe 3 Si trilayer structures. The kink which develops between M/M s = 0 and 0.5 with increasing spacer thickness indicates a progressing magnetic decoupling of the ferromagnetic layers [40][41][42]. For even larger spacer thicknesses, this kink is expected to develop into a step in the magnetization curve as a signature of fully independent magnetization reversals in the two decoupled ferromagnetic electrodes.…”
