Ferh irradiation
WebMay 7, 2014 · Since the ion beam irradiation induced magnetization of FeRh is significantly correlated with the amount of the lattice defects in the samples, cluster ion beam irradiation can be considered to effectively introduce the lattice defects in B2-type FeRh rather than the single ion beam. WebWe previously reported that the ion beam irradiation at various energies ranging from GeV to keVorders can induce the FM state in FeRh bulk and film samples without any structural changes below room temperature at which they are originally in the AF state.15,16) In addition, further ion beam irradiation causes the change from the FM state to the

WebIron–rhodium (FeRh) thin films were irradiated with a 30 keV Ga ion beam using a focused ion beam system to produce micrometer scale ferromagnetic square dot arrays. Two-dimensional magnetic square dot arrays with dimensions of 30 × 30, 10 × 10, and 5 × 5 μm were successfully produced on the FeRh surface, which was confirmed by magnetic ... WebWith these irradiation conditions, the ions have an aver-age penetration equal to half the thickness of the FeRh layer and are deposited in all its volume. At this en-ergy, the nuclear elastic collisions between ions and FeRh atoms are the predominant processes [30]. They mainly induce point-like defect vacancies or interstitial atoms.

WebFeb 3, 2024 · The ordered FeRh near-equiatomic composition adopts CsCl structure and undergoes a paramagnetic to ferromagnetic (FM) transition at around 670 K and a ferromagnetic to antiferromagnetic (FM–AFM) transition at around 370 K [ 4, 5 ].
WebIt was clearly shown in the magnetization loops by SQUID measurements that the ion irradiation induced the ferromagnetic state in the FeRh thin films even below room temperature. This was also confirmed by the Fe L 2,3-edge XMCD measurements for the irradiated FeRh film samples. However, we found that the irradiation ion fluence …
