TL;DR: This finding allows the physics of antiferromagnetic spin dynamics to be investigated and highlights the importance of tuning of the angular momentum compensation point of ferrimagnets, which could be a key towards ferrimagnetic spintronics.

TL;DR: In this article, fast field-driven antiferromagnetic spin dynamics is realized in ferrimagnets at the angular momentum compensation point TA, using rare-earth 3d-transition metal ferrimagnetic compounds where net magnetic moment is nonzero at TA.

TL;DR: In this paper, the temperature dependence of magnetoresistance was investigated in ferrimagnetic GdFeCo/Pt heterostructures and an anomalous Hall effect (AHE) showed a monotonic behavior in temperature even across the magnetization compensation temperature T M, implying that the FeCo moment is responsible for the magnetotransport properties.

TL;DR: In this paper, the authors investigated the field-driven magnetic domain wall (DW) motion in ferrimagnetic GdFeCo wires with perpendicular magnetic anisotropy and found that the DW velocity as a function of the out-of-plane magnetic field exhibited the Walker breakdown phenomenon.

TL;DR: In this paper, an X-ray tomographic technique was developed to investigate the internal magnetic domain structure in a micrometer-sized ferromagnetic sample, based on a scanning hard Xray nanoprobe using Xray magnetic circular dichroism (XMCD).
