Electronic Structure of La(Fe0.88Si0.12)13
La(Fe0.88Si0.12)13 shows peculiar magnetic properties such as the first order paramagnetic-ferromagnetic transition and magnetic-field induced metamagnetic transition accompanied by the lattice expansion. The pra...

Antiferromagnetism of Mn Alloys
Most Mn alloys exhibit antiferromagneto properties due to their occupation of 3d orbitals close to half-filling. There are many systems having a complex (non-collinear) magnetic structure, depending on the num...

Magnetic Properties of Quasicrystals
After the discovery of an icosahedral (I) Al-Mn phase (Shechtman et al. 19841), there was immediately great interest in determining whether similar phases would form in other alloy systems. A number of quasicryst...

Magnetic and Transport Properties of Micron Size Magnetic Participate Arrays Fabricated on a 2D Superconducting Nb Films and Sub-Micron Magnetic Wires
Micron size particulate arrays of amorphous R-Co (R = Sm and Gd) alloys with a thickness of 200 nm were fabricated on top of a 20 nm thick Nb film by means of e-beam lithography and sputter deposition. The arr...

Diffusion of 57Co in amorphous Fe-RE (RE = Dy, Tb, and Ce) and Fe-Si-B alloys
Tracer diffusion of 57Co in amorphous Fe100−xDyx (x = 20–40), Fe75Tb25, Fe67Ce33, and Fe80Si6B14 alloys prepared by dc sputtering has been studied at temperatures of 523 and 573 K. In the Fe-Dy alloys the diffusi...
