The search for novel materials exhibiting non-trivial properties is the main task of solid state research. Ranging from high temperature superconductivity over quantum computers, novel batteries to spintronics and multi-functional materials, this field spans a wide range of disciplines and material types. One specific field of interest within magnetism is multiferroicity where especially...
Interactions of critical fluctuations in combination with an increased phase space may drive a second order phase transition first order. Using small angle neutron scattering (SANS) and modulation of intensity with zero effort (MIEZE) spectroscopy in combination with measurements of the magnetic, thermodynamic, and transport properties, we have investigated the fluctuation-induced first-order...
Yttrium iron garnet (Y$_3$Fe$_5$O$_{12}$) has, since its discovery in 1957, fundamentally contributed to the development of important research fields such as spintronics, magnonics and hybrid quantum information systems. Iron garnets incorporating magnetic rare-earth ions are relatively less well-known, but have also been studied for their interesting spin transport phenomena, magnetoelectric...
Most of the spiral magnetoelectric multiferroics investigated in recent years are geometrically or exchange frustrated magnets with low magnetic transition temperatures. The exceptional stability of the spiral magnetic order (at T$_S$) in the layered structure of YBaCuFeO$_5$ [1,2] involves a non-conventional mechanism (“spiral order by disorder”) theoretically developed by Scaramucci et al....
Skyrmions are topologically non-trivial spin textures that exhibit an exceptionally efficient coupling to spin currents, notably spin-polarized charge currents and magnon currents as observed in MnSi, FeGe, and Cu2OSeO3 [1, 2, 3]. This raises the question for the microscopic mechanisms that control the pinning of the skyrmion lattice, and how they depend on the topology, electronic structure,...
