“…Thus, R DG (T) behavior is driven by an interplay of these two effects and as a result, the value R DG (T) for Mn x Si 1-x (x ≈ 0.52) film below ∼ 40 K significantly exceeds R SC (T) for ε-MnSi, where R SC (T) falls down dramatically. 24 The physical origin of this remarkable phenomenon of simultaneous increase of carrier mobility and decrease of carrier concentration at the doping of single crystal ε-MnSi with additional Mn atoms is not yet clear. A possible (but certainly open to discussions) reason qualitatively explaining experimental data has been proposed in Ref.…”

“…It presumes that: 1) the Mn doping induces the carrier localization on the defect center (e.g., the above discussed Si vacancy) in the MnSi matrix; 2) this doping also destroys collective (spin-polaron or Kondo type) resonance, probably existing in ε-MnSi single crystal. 24 The combination of these two effects obviously leads to the simultaneous decrease…”

“…In Fig. 10, the normalized temperature dependences R(T) = R SG (T) and R(T) = R DG (T) (taken from 3 ) are shown, respectively, for DG (d ≈ 70 nm; x ∼ 0.52) and SG (d ≈ 70 and 160 nm; x ∼ 0.52) grown Mn x Si 1-x films, in comparison with R(T) = R SC (T) for ε-MnSi single crystal (taken from 24 ). From the data presented in Fig.…”

Absence of anomalous Nernst effect in spin Seebeck effect of Pt/YIG AIP Advances 6, 015018 (2016); 10.1063/1.4941340Dual resonant structure for energy harvesting from random vibration sources at low frequency AIP Advances 6, 015019 (2016) The results of a comprehensive study of magnetic, magneto-transport and structural properties of nonstoichiometric Mn x Si 1-x (x≈0.51-0.52) films grown by the Pulsed Laser Deposition (PLD) technique onto Al 2 O 3 (0001) single crystal substrates at T = 340 • C are present. A highlight of used PLD method is the non-conventional ("shadow") geometry with Kr as a scattering gas during the sample growth. It is found that the films exhibit high-temperature (HT) ferromagnetism (FM) with the Curie temperature T C ∼ 370 K accompanied by positive sign anomalous Hall effect (AHE); they also reveal the polycrystalline structure with unusual distribution of grains in size and shape. It is established that HT FM order is originated from the bottom interfacial self-organizing nanocrystalline layer. The upper layer adopted columnar structure with the lateral grain size ≥ 50 nm, possesses low temperature (LT) type of FM order with T c

“…The B − T phase diagram of MnSi has been extensively studied experimentally [7,[26][27][28][29][30][31][32] and by MCS [33]. In this system, the SkL is only stable at finite temperature and magnetic field, in a small pocket of the phase diagram.…”

We determined the magnetic B − T phase diagram of PdFe bilayer on Ir(111) surface by performing Monte Carlo and spin dynamics simulations based on an effective classical spin model. The parameters of the spin model were determined by ab initio methods. At low temperatures we found three types of ordered phases, while at higher temperatures, below the completely disordered paramagnetic phase, a large region of the phase diagram is associated with a fluctuation-disordered phase. Within the applied model, this state is characterized by the presence of skyrmions with finite lifetime. According to the simulations, this lifetime follows the Arrhenius law as a function of temperature.
