Spin glass behavior in FeAl2

Magnetic and transport measurements indicate FeAl2 to be an ordered intermetallic spin glass, with canonical behavior including a susceptibility cusp at T f535 K and frequency-dependent susceptibility below T f . The field-cooled and zero-field-cooled magnetization diverge below T f , with hysteresis characteristic of a spin glass. A resistivity minimum just above T f is explained in terms of c...

Strong magnetic frustration and anti-site disorder causing spin-glass behavior in honeycomb Li2RhO3.

With large spin-orbit coupling, the electron configuration in d-metal oxides is prone to highly anisotropic exchange interactions and exotic magnetic properties. In 5d(5) iridates, given the existing variety of crystal structures, the magnetic anisotropy can be tuned from antisymmetric to symmetric Kitaev-type, with interaction strengths that outsize the isotropic terms. By many-body electronic...

Spin-glass behavior of semiconducting KxFe2− yS2

We report the discovery of KxFe2−yS2 single crystals, isostructural to KxFe2−ySe2 superconductors. The sulfide compound is a small gap semiconductor and shows spin-glass behavior below 32 K. Our results indicate that stoichiometry, defects, and the local environment of FeCh (Ch = S,Se) tetrahedra have important effects on the physical properties of isostructural and isoelectronic KxFe2−yCh2 com...
