In this presentation, we will explore the complex magnetic behaviour of Ho-doped langasite ([La$_{1−x}$Ho$_x$]$_3$Ga$_5$SiO$_{14}$), focusing on understanding how local structural distortions influence the ising-like Ho3+ moments and ultimately the macroscopic magnetoelectric properties. The study leverages complementary experimental evidence, combining polarised neutron diffraction and...
Ferrotoroidicity is the fourth ferroic order characterized by the simultaneous breaking of both time and space-reversal symmetries [1]. The intrinsic magnetoelectric effect associated with this order makes it interesting for energy-efficient memory devices. The ability to pole and control ferrotoroidal domains could prove important for non-volatile and high-density data storage applications....
The low ordering temperatures of most non-collinear spiral magnets critically limits their implementation in devices. The layered perovskites LnBaCuFeO$_5$ are a rare case of frustrated oxide family that has raised great expectation as promising high-temperature spiral magnets and chiral spin-driven multiferroic candidates. Though a novel mechanism (“Spiral order by disorder”) seems to...
Magnonics is a multidisciplinary field of research focusing on the study and application of magnons in information processing and technology [1]. Magnons can carry the spin information through thermally generated spin-wave spin currents over the large distances [2]. Insulating antiferromagnets (AFMs) are promising for next-generation high-density and high-speed spintronic applications due to...
