Fully Compensated Lines in Ferrimagnets
Qais Ali, Anna Grünebohm, Halil Ibrahim Sözen +3
We generalize the classic Néel diagram and identify another type of ferrimagnetic phase that remains fully magnetically compensated below the Curie temperature, forming a continuou…
Caloric properties of materials near a tricritical point
Eduardo Mendive-Tapia, Antoni Planes
We present a mean-field study of caloric effects driven by primary and secondary fields near tricritical points, which are fields thermodynamically conjugated to the main and secon…
Fermi-surface origin of skyrmion lattices in centrosymmetric rare-earth intermetallics
Juba Bouaziz, Eduardo Mendive-Tapia, Stefan Blügel +1
We show from first-principles that barrel-shaped structures within the Fermi surface of the centrosymmetric intermetallic compounds GdRuSi and GdPdSi give rise to F…
Ab initio calculation of the magnetic Gibbs free energy of materials using magnetically constrained supercells
Eduardo Mendive-Tapia, Jörg Neugebauer, Tilmann Hickel
We present a first-principles approach for the computation of the magnetic Gibbs free energy of materials using magnetically constrained supercell calculations. Our approach is bas…
Ab initio investigations of point and complex defect structures in B2-FeAl
Halil İbrahim Sözen, Tilmann Hickel, Jörg Neugebauer
In this work we have studied the defect structure and corresponding defect concentration investigations through the theoretical, experimental and computational works on B2-type Fe-…
Short period magnetization texture of B20-MnGe explained by thermally fluctuating local moments
Eduardo Mendive-Tapia, Manuel dos Santos Dias, Sergii Grytsiuk +3
B20-type compounds, such as MnSi and FeGe, host helimagnetic and skyrmion phases at the mesoscale, which are canonically explained by the combination of ferromagnetic isotropic int…
Caloric effects around phase transitions in magnetic materials described by ab initio theory: The electronic glue and fluctuating local moments
Eduardo Mendive-Tapia, Julie B. Staunton
We describe magneto-, baro- and elastocaloric effects (MCEs, BCEs and eCEs) in materials which possess both discontinuous (first-order) and continuous (second-order) magnetic phase…
First-order ferromagnetic transitions of lanthanide local moments in divalent compounds: An itinerant electron positive feedback mechanism and Fermi surface topological change
Eduardo Mendive-Tapia, Durga Paudyal, Leon Petit +1
Around discontinuous (first-order) magnetic phase transitions the strong caloric response of materials to the application of small fields is widely studied for the development of s…
Ab initio theory of the Gibbs free energy and a hierarchy of local moment correlation functions in itinerant electron systems: The magnetism of MnA materials class
Eduardo Mendive-Tapia, Julie B Staunton
We present an \textit{ab-initio} disordered local moment theory for the Gibbs free energy of a magnetic material. Two central objects are calculated: the lattice Fourier transform…
Rare-earth/transition-metal magnetic interactions in pristine and (Ni,Fe)-doped YCo5 and GdCo5
Christopher E. Patrick, Santosh Kumar, Geetha Balakrishnan +5
We present an investigation into the intrinsic magnetic properties of the compounds YCo5 and GdCo5, members of the RETM5 class of permanent magnets (RE = rare earth, TM = transitio…
Magneto- and Baro- Caloric Responses in Magnetovolumic Systems
Eduardo Mendive-Tapia, Teresa Castán
By means of a mean-field model extended to include magnetovolumic effects we study the effect of external fields on the thermal response characterized either by the isothermal entr…
