    • 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 ...
    • 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 ...
