Increasing Temperature

The Tm2Fe17 compound has been studied by means of powder neutron diffraction. The compound undergoes a spin-reorientation transition (SRT) of the “easy axis – easy plane” type with increasing temperature from 75 K to 100 K. The SRT is accompanied by a distinct anomaly in the temperature dependencies of the Tm- and Fe-ion magnetizations, significative of large magnetization anisotropy. Using three sublattices model, the parameter of the Tm-Fe interaction and constants of magnetic anisotropy are determined.

Ordered State

The magnetic anisotropy (MA) of trihydrides of single-crystalline rare-earth (R) intermetallics R2Fe17H3±x (R = Tb and Dy) with small deviations in the hydrogen concentration (x = 0 – 0.4) was investigated via the magnetic and magnetoelastic measurements in a wide temperature region. The easy-axis MA of Tb2Fe17H3±x is preserved in the entire range of magnetically ordered state while an “easy-cone – easy-plane” transition takes place in Dy2Fe17H3±x above ambient temperatures. The trihydrides demonstrate a significant decrease of magnetic anisotropy as the temperature increases. The temperature variation of thermal expansion of Dy2Fe17H3 displays anomalies in the vicinity of a spin-reorientation transition. The longitudinal magnetostriction λ||(T) of the same compound changes its sign at 340 K. The compounds studied can find specific applications in practice.

Magnetic Modification

The microstructure of Co/Pt multilayers with large perpendicular magnetic anisotropy (PMA) was investigated before and after energetic ion irradiation. No pronounced microstructural changes were detected at ion doses sufficient to completely reduce the PMA and cause a spin reorientation transition to in-plane. Ion-induced displacement of Co and Pt atoms near Co/Pt interfaces lead to local “roughening” and Co layer strain relaxation, reducing the PMA. The magnetic domain confinement induced by ion irradiation and magnetic patterning by selective ion irradiation were also investigated.
