“…On the other hand, the Mn x Si 1-x (x≈0.5) thin layers grown on Si(001) or Al 2 O 3 (0001) substrates demonstrate the high-temperature (HT) ferromagnetism (FM) with the Curie temperature T c of the order of room temperature. [2][3][4] This fact is in contrast to the case of bulk ε-MnSi single crystal, where only the low-temperature (LT) FM was reported with T C ≈ 30 K. 8,9 The HT FM order at x 0.506 (that just corresponds to the single crystal ε-MnSi belonging to berthollides 9,10 ) was observed in the Mn x Si 1-x /Si(001) structures but at enough small Mn x Si 1-x film thickness less than one ε-MnSi monolayer. 2,11 This order is explained by the formation of c-MnSi phase with B2-like (CsCl) crystal structure stabilized with tetragonal distortion due to favorable lattice mismatch between the film and substrate.…”

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

“…However, the measurements of a complex of not only thermal but also of 'pure' lattice properties of iron and cobalt monosilicides, which were carried out afterwards, have shown that the properties of these compounds are essentially different [13]. Therefore, there is no reliable information on the temperature dependence of the electronic heat capacity of FeSi, the correlation of which with the data on magnetic susceptibility is of principal interest for testing possible models of the electronic structure of FeSi [14].…”

Abstract:Although chiral magnetic materials have emerged as a potential ingredient in future spintronic memory devices, there are few comprehensive studies of magnetic properties in scalably-grown thin films. We present growth, systematic physical and magnetic characterization, and microwave absorption spectroscopy of B20 FeGe thin films. We also perform micromagnetic simulations and analytical theory to understand the dynamical magnetic behavior of this material. We find magnetic resonance features in both the helical and fieldpolarized magnetic states that are well explained by micromagnetic simulations and analytical calculations. In particular, we show the resonant enhancement of spin waves along the FeGe film thickness that has a wave vector matching the helical vector. Using our analytic model, we also describe the resonance frequency of a helical magnetic state, which depends solely on its untwisting field. Our results pave the way for understanding and manipulating high frequency spin waves in thin-film chiral-magnet FeGe near room temperature.
