Stability of Mn2RuxGa-based Multilayer Stacks
Gwenael Atcheson, Katarzyna Siewierska, J. M. D. Coey +2
Perpendicular heterostructures based on a ferrimagnetic Mn2RuxGa (MRG) layer and a ferromagnetic Co/Pt multilayer were examined to understand the effects of different spacer layers…
New highly-anisotropic Rh-based Heusler compound for magnetic recording
Yangkun He, Gerhard H. Fecher, Chenguang Fu +18
The development of high-density magnetic recording media is limited by the superparamagnetism in very small ferromagnetic crystals. Hard magnetic materials with strong perpendicula…
Sub-picosecond exchange-relaxation in the compensated ferrimagnet MnRuGa
G. Bonfiglio, K. Rode, G. Y. P. Atcheson +5
We study the demagnetization dynamics of the fully compensated half-metallic ferrimagnet MnRuGa. While the two antiferromagnetically coupled sublattices are both composed o…
Imaging Domains in a Zero-Moment Half Metal
K. E. Siewierska, N. Teichert, R. Schäfer +1
We have a choice of methods for examining domains at the surface of a ferromagnet that depend on probing the stray field distribution, but these methods do not work in antiferromag…
d-zero Magnetism in Nanoporous Amorphous Alumina Membranes
Amir Sajad Esmaeily, M. Venkatesan, S. Sen +1
Nanoporous alumina membranes produced by mild or hard anodisation in oxalic acid at potentials ranging from 5 - 140 V have a controllable pore surface area of up to 200 times the m…
Exchange coupling of a perpendicular ferromagnet to a half-metallic compensated ferrimagnet via a thin hafnium interlayer
Kiril Borisov, Gwenaël Atcheson, Gavin D'Arcy +3
A thin Hafnium film is shown to act both as an effective diffusion barrier for manganese at a thickness of 0.7 nm, and as an effective exchange coupling layer in a sandwich structu…
