• Effect of oxygen partial pressure on the density of antiphase boundaries in Fe3O4 thin films on Si(100) 

      Singh, Suraj Kumar; Husain, Sajid; Kumar, Ankit; Chaudhary, Sujeet (Journal article; Peer reviewed, 2018)
      Polycrystalline Fe3O4 thin films were grown on Si(100) substrate by reactive DC sputtering at different oxygen partial pressures for controlling the growth associated density of antiphase boundaries (APBs). The micro-Raman ...
    • Magneto-dynamic properties of complex oxide—La0.7Sr0.3MnO3/SrTiO3— heterostructure interface 

      Singh, Suraj Kumar; Bolstad, Torstein; Hallsteinsen, Ingrid; Tybell, Per Thomas Martin; Wahlström, Erik (Journal article; Peer reviewed, 2019)
      We have studied the interface magnetodynamic properties of La0.7Sr0.3MnO3/SrTiO3 (111) heterostructures by Ferromagnetic resonance spectroscopy (FMR). In addition to the bulk FMR mode, the measurements indicate a mode ...
    • Magneto-dynamic properties of thin films and interfaces 

      Singh, Suraj Kumar (Doctoral theses at NTNU;2020:278, Doctoral thesis, 2020)
      Magnonics is a developing branch in the field of condensed matter physics with the potential to fulfill the future demand for miniaturized, fast, and energy-efficient spintronics devices. This thesis explores both a novel ...
    • Magnetodynamic properties of dipole-coupled 1D magnonic crystals 

      Singh, Suraj Kumar; Wang, Xiansi; Kumar, Ankit; Qaiumzadeh, Alireza; Svedlindh, Peter; Tybell, Per Thomas Martin; Wahlström, Erik (Journal article, 2021)
      Magnonic crystals are magnetic metamaterials, that provide a promising way to manipulate magnetodynamic properties by controlling the geometry of the patterned structures. Here, we study the magnetodynamic properties of ...
    • Propagation properties of spin wave in Co2FeAl Heusler alloy ultrathin films 

      Singh, Suraj Kumar; Gupta, Nanhe Kumar; Hait, Soumyarup; Chaudhary, Sujeet; Tybell, Thomas; Wahlström, Erik (Peer reviewed; Journal article, 2021)
      We report an investigation of spin wave propagation in ion beam sputtered Co2FeAl Heusler alloy thin film on Si(100) substrate. The spin wave transmission spectra measured at fixed frequencies by sweeping the external ...
