Dzyaloshinskii-Moriya interaction in absence of spin-orbit coupling
Ramon Cardias, Anders Bergman, Attila Szilva +5
In contrast to conventional assumptions, we show that the Dzyaloshinskii-Moriya interaction can be of non-relativistic origin, in particular in materials with a non-collinear magne…
Self-induced spin glass state in elemental and crystalline neodymium
Umut Kamber, Anders Bergman, Andreas Eich +8
Spin glasses are a highly complex magnetic state of matter, intricately linked to spin frustration and structural disorder. They exhibit no long-range order and exude aging phenome…
Systematic study of the hidden order in URuSi as a multipolar order; the role of triakontadipoles
Oscar Granas, Francesco Cricchio, Lars Nordstrom
A systematic search for possible order parameters of the so-called hidden order of URuSi is conducted. Among the possible candidates that do fulfill the experimental sy…
The low spin moment in LaOFeAs is due to a hidden multipole order caused by spin orbital ordering
Francesco Cricchio, Oscar Granas, Lars Nordstrom
An antiferro-magnetic (AF) low moment solution, 0.4 /Fe, is found in the case of LaOFeAs for an intermediately strong Coulomb interaction of 2.5--3.0 eV. This sol…
Atomistic spin dynamics of the CuMn spin glass alloy
B. Skubic, O. E. Peil, J. Hellsvik +3
We demonstrate the use of Langevin spin dynamics for studying dynamical properties of an archetypical spin glass system. Simulations are performed on CuMn (20% Mn) where we study t…
Magnetic properties of LaOFFeAs
S. Sharma, J. K. Dewhurst, S. Shallcross +6
Using state-of-the-art first-principles calculations we have elucidated the complex magnetic and structural dependence of LaOFeAs upon doping. Our key findings are that (i) doping…
