Interplay of structure and magnetism in LuFe4Ge2 tuned by hydrostatic pressure
M. O. Ajeesh, P. Materne, R. D. dos Reis +15
LuFeGe crystallizes in the ZrFeSi-type structure, hosting chains of Fe-tetrahedra giving rise to geometric frustration and low-dimensionality. The compound orders a…
Destruction of long-range magnetic order in an external magnetic field and the associated spin dynamics in Cu2GaBO5 and Cu2AlBO5 ludwigites
A. A. Kulbakov, R. Sarkar, O. Janson +12
The quantum spin systems CuM'BO (M' = Al, Ga) with the ludwigite crystal structure consist of a structurally ordered Cu sublattice in the form of three-leg ladders,…
Quantum spin liquid ground state in the disorder free triangular lattice NaYbS
R. Sarkar, Ph. Schlender, V. Grinenko +4
Rare-earth delafossites were recently proposed as promising candidates for the realization of an effective =1/2 quantum spin liquid (QSL) on the triangular lattice. In contrast…
Disordered magnetism in the double perovskite LaCaScIrO6 with a distorted fcc lattice of Ir4+
M. Vogl, G. Bastien, R. Sarkar +9
The synthesis and characterization of the previously unknown material LaCaScIrO is reported. LaCaScIrO presents a new example of the rare case of a double perovskite with t…
Magnetic Field tuning of low energy spin dynamics in the single-atomic magnet Li(LiFe)N
S. A. Braeuninger, A. Jesche, S. Kamusella +5
We present a systematic 57Fe-Moessbauer study on highly diluted Fe centers in Li2(Li1-xFex)N single-crystals as a function of temperature and magnetic field applied transverse and…
Anomalous Knight shift and low-energy spin dynamics in the nematic state of FeSeS
V. Grinenko, S. Dengre, R. Sarkar +8
The interplay between the nematic order and magnetism in FeSe is not yet well understood. There is a controversy concerning the relationship between orbital and spin degrees of fre…
