We studied MgO barrier magnetic tunnel junctions (MTJs) comprising perpendicularly magnetized MnGa and FeCoB electrodes. In those perpendicular (p-) MTJs, we utilized thin metastable bcc CoMn alloys as an interlayer between MnGa and MgO to enhance th

Aromatic hydrocarbon macrocycles, which have a conjugated π-electron system, are potentially useful for various organic device applications, although there have been no attempts to apply them to organic spin valves (OSVs). Here, we studied OSVs w

The longitudinal spin-Seebeck effect (LSSE) has been investigated in cobalt ferrite (CFO), an exceptionally hard magnetic spinel ferrite. A bilayer of a polycrystalline Pt and an epitaxially-strained CFO(110) exhibiting an in-plane uniaxial anisotrop

The magnetic atom diffusion at the interface between CoMn alloy and MnGa layer with annealing is studied using x-ray magnetic circular dichroism (XMCD) analysis. We found that the spins in bcc CoMn are coupled parallel to those in perpendicularly mag

A magnetic nanolayer with a perpendicular magnetic easy axis and negligible magnetization is demonstrated. Even though a manganese metal is antiferromagnetic in bulk form, a few manganese monolayers grown on a paramagnetic ordered alloy template and

We have investigated the magnetic properties of cobalt ferrite films epitaxially grown on MgAl 2 O 4 (110) substrates. The unit cell of the cobalt ferrite film on the substrate with twofold surface symmetry is tetragonally distorted with c/a

Thin films of NiFe 2 O 4 were fabricated on MgO (001) and MgAl 2 O 4 (MAO) (001) substrates by reactive radio frequency magnetron sputtering and were evaluated with regards to their electrical and magnetic properties. A saturation magnetization of 28

Recently, we reported on the synthesis of a high-quality polyimide-Co (PI-Co) granular thin film using vapor deposition polymerization. This thin film had a tunnel magnetoresistance (TMR) ratio of 2.6% at room temperature. Because thermal annealing i
