To realize rare-earth-free magnets, we studied iron nitride (α″-Fe16N2) magnets, which contain no rare-earth elements. Fe-N powder with the α″-Fe16N2 phase has a high saturation magnetization comparable to high-performance rare-earth magnets bu

It would be desirable if the magnetic properties of Sm–Fe alloys could be increased without the need for nitrogenation. In this experiment, Sm–Fe bulk magnets were prepared from the Sm–Fe powders by the spark plasma sintering (SPS) technique wi

Mn-based magnets are known to be a candidate for use as rare-earth-free magnets. In this study, Mn-Ga bulk magnets were successfully produced by hot pressing using the spark plasma sintering method on Mn-Ga powder prepared from rapidly solidified Mn-

The large anomalous Hall (AHE) and anomalous Nernst effects (ANE) in antiferromagnets Mn3Sn/Mn3Ge are considered fingerprints of Weyl nodes residing near the Fermi energy. Here, the authors review the results from previous studies combining with new

In this study, we synthesized Mn65Ga35-δBδ (δ = 0–10) alloys using the melt-spinning technique. In the as-quenched state, the alloys consisted of the D019 and Mn8Ga5 phases in the as-quenched state. After heat treatments, the Mn65Ga35 alloy cons

Tetragonal FeAl2 is a high-pressure phase and is predicted to exhibit semiconductor-like behavior. We investigated the pressure and temperature synthesizing conditions of tetragonal FeAl2, supported by in situ X-ray diffractions, using synchrotron ra

The tunnelling electric current passing through a magnetic tunnel junction (MTJ) is strongly dependent on the relative orientation of magnetizations in ferromagnetic electrodes sandwiching an insulating barrier, rendering efficient readout of spintro

Rh-rich and Ir-poor erlichmanite–laurite OsS2–RuS2 solid solutions have been discovered at placers in Haraigawa, Misato-machi, Kumamoto, Japan. Microprobe analysis was performed to identify solid solutions containing few sub-components other than
