Restoration of ion beam irradiation induced metastable magnetic states and lattice structures of FeRh thin films by heat treatments at elevated temperatures

A Three-Dimensional Analysis of Magnetic Nanopattern Formation in FeRh Thin Films on MgO Substrates: Implications for Spintronic Devices

“…Recently, several studies have been published on tailoring the magnetic and structural properties of FeRh by ion irradiation. A wide variety of ions and energies such as 30 keV Ga + , 1 MeV proton, 20 keV Ne + , 120 keV Ne + , 10 MeV I + , , 50 keV Ar + , 5 keV N + , or 3.8 keV He + were applied to manipulate the FM–AFM, FM–PM transition, as well as to induce the B2 → A1 structural transformation. By the manipulation of magnetic phases using 25 keV Ne + irradiation, simultaneous coexistence of three magnetic phases (FM, PM, and AFM) was demonstrated .…”

Ion Accelerator Facility of the Wakasa Wan Energy Research Center for the Study of Irradiation Effects on Space Electronics

“…The accelerator facility consists of three accelerators: a synchrotron, a tandem accelerator and an ion-implanter [1,2]. Using these accelerators, we have been involved in research on the destruction of tumor cells in human bodies (proton beam radiotherapy) [3,4], the transmutation of DNAs in plants and bacteria (ion beam breeding) [5][6][7], ion beam material modification [8][9][10] and ion beam analysis for materials [11][12][13]. The accelerators at WERC have also been utilized to simulate the radiation effects on materials which are related to nuclear power plants [14][15][16] and those of space electronics [17][18][19][20][21][22][23][24][25].…”
