    • Acoustoelectric drag current in vanadium oxide films 
      Lapa, Pavel N.; Kassabian, George; Torres, Felipe; Salev, Pavel; Lee, Min-Han; Valle, Javier del; Schuller, Iván K. (American Physical Society, 2020)
      Two different Mott insulator wires, vanadium dioxide and vanadium sesquioxide, were prepared on the piezoelectric LiNbO3 substrates. Coupling of acoustic waves propagating in LiNbO3 with free carriers in vanadium oxide ...
    • Chiral symmetry and scale invariance breaking in spin chains 
      Torres, Felipe; Kiwi Tichauer, Miguel; Vargas, Nicolás M.; Monton, Carlos; Schuller, Iván K. (The American Institute of Physics, 2020)
      The effects of the Dzyaloshinsky-Moriya interaction on finite size one-dimensional (1D) magnetic chains are investigated as a function of their length. The magnetic configuration the system adopts for varying boundary ...
    • Enhanced positive and negative exchange bias in FeF2/Ni with dusted interfaces 
      Montoya, I.; Torres Sánchez, Felipe; Redondo, C.; Kiwi Tichauer, Miguel; Schuller, Iván K.; Morales R., Mónica (American Institute of Physics, 2020)
      An enhanced exchange bias was found in FeF2/Ni interfaces by inserting dusting of Pd and Cu atoms. We have used an ultrathin wedge to investigate systematically the effect of a discontinuous nonmagnetic spacer between the ...
    • Helical spin structure in iron chains with hybridized boundaries 
      Vargas, Nicolás M.; Torres, Felipe; Baker, Alexander A.; Lee, Jonathan R. I.; Kiwi Tichauer, Miguel; Willey, Trevor M.; Monton, Carlos; Schuller, Iván K. (American Institute of Physics, 2020)
      We have compared the magnetic properties of well-controlled ultra-short (<= 50nm) atomic iron (Fe) chains embedded in Fe-phthalocyanine films with those in Fe-hydrogen (H-2) phthalocyanine superlattices. Surprisingly, we ...
