We have used resistivity measurements to study the magnetic phase diagram of the itinerant antiferromagnet FeGe_2 in the temperature range from 0.3->300 K in magnetic fields up to 16 T. In contrast to theoretical predictions, the incommensurate spin density wave phase is found to be stable at...
Here, we report the direct observation of ChBs in thin films of B20-type FeGe by means of quantitative off-axis electron holography (EH). We identify the part of the temperature–magnetic field phase diagram in which ChBs exist and distinguish two mechanisms for their nucleation. Furthermore, ...
The aim of the present study was determining the phase relations in the FeGa2Se4-FeIn2Se4 system. We used the differential thermal analysis (DTA) and X-ray diffraction (XRD) in order to analyze the samples of the system. The temperatures of the thermal effects were determined using a ...
For our studies on the dynamics of topological magnetic defects, we choose cubic FeGe37 as it exhibits helimagnetic order near room temperature with TN≈280 K and because its phase diagram is well-characterized38. Single crystals of FeGe were grown by the chemical vapour transport method39 a...

Similar to the hexagonal FeGe, we captured a structural phase transition in the monoclinic FeGe films at 100K in real and reciprocal spaces by transmission electron microscope. Our work enriches the phase diagram of the FeGe family and suggests that FeGe offers an ideal platform for studying ...
Moreover, these data revealed independent and clear indications of phase boundaries and crossovers within the A-phase region. Together with the anomalies in the specific-heat data around Tc and at small magnetic fields (H<600 Oe) a complex magnetic phase diagram of FeGe is obtained.doi:10.1002...
Thus, the precise phase diagram near T c was reconstructed from the prospect of the magnetostriction such that we demonstrated that the stabilization of skyrmions needs a finite magnetic field.Masaki MitoTakayuki TajiriYusuke KousakaMarina Miyagawa...
It is shown that the phase diagram we found for the helimagnet is analogous to the phase diagram of the superconductors of second kind in the magnetic field, where the A-phase is a counterpart of the superconducting mixed state with the Abrikosov vortices....
