Strain-induced modification in the magnetic properties of Mn5Ge3 .Epitaxial ferromagnetic Mn5 Ge 3 thin films were stabilized on GaSb(001) and GaAs(001) substrates using molecular beam epitaxy. Compared to bulk Mn5 Ge 3 materials, an enhancement of the Curie temperature above 350 K and about 320 K was observed for Mn5 Ge 3/GaAs(001) and Mn5 Ge 3/GaSb(001).magnetic properties modification,Modification in Structural and Magnetic Properties of Pure ZnO .ZnO have been fabricated using co-precipitation method. The molecular weights of the precursor's chlorides were used to adjust composition. The pure ZnO sample exhibited single phase, while, the sample with xBi = 0.02 resulted phase separation into the formation of BiCl3 peak. The room temperature ferromagnetism.

Boundary structure modification and magnetic properties of Nd-Fe-B .

In this paper, the effect of Dy2O3/S co-doping on the magnetic properties and microstructure was studied in Nd-Fe-B sintered magnets. With S co-doping, the coercivity increased due to grain boundary modification and Dy selective introduction. Continuous grain boundary phases were formed in the co-doped magnets with.

Modification of magnetic properties of Pt/Co/Pt trilayers driven by .

Nov 30, 2016 . Modifications of magnetic properties of the Co/Pt multilayers grown on sapphire (0 0 0 1) substrate with a light illumination were shown in [15]. A 10 ns laser single pulse with a wavelength of 532 nm and fluence of 190 mJ cm−2 can partially melt the multilayer. As a result, a reduction of the magnetic.
