Control of topological spin textures in magnetic systems may enable future spintronic
applications. Magnetic field pulses can switch the vortex polarity or the winding number of …

Nonreciprocal flow of conduction electrons is systematically investigated in a monoaxial
chiral helimagnet C r N b 3 S 6. We found that such directional dichroism of the electrical …

Magneto-chiral dichroism (MChD) is an interesting phenomenon in which the absorbance of
a chiral molecule depends on the direction of the magnetic field. As the MChD of two …

Magnetochiral dichroism (MChD) in chiral materials is a nonreciprocal directional dichroism
producing optical absorption/emission differences for unpolarized (or linearly polarized) light …

In magnetoelectric materials, where the time-reversal and space-inversion symmetries are
simultaneously broken, optical properties can differ between the opposite propagation …

Copper metaborate CuB 2 O 4 crystallizes in a unique noncentrosymmetric structure,
becomes antiferromagnetically ordered below T N1= 20 K, and exhibits a great diversity in …

We present a microwave electron spin resonance study of the quantum spin dimer system
TlCuCl 3, which shows the magnetic-field-induced ordering with both antiferromagnetic spin …

Spin excitations of magnetoelectric LiNiPO 4 are studied by infrared absorption
spectroscopy in the THz spectral range as a function of magnetic field through various …

We have investigated the microwave nonreciprocity for a noncentrosymmetric
antiferromagnet Ba 2 MnGe 2 O 7. The magnon modes expected by the conventional spin …

We observed surface acoustic wave (SAW) propagation on a multiferroic material CuB 2 O 4
with use of two interdigital transducers (IDTs). The period of IDT fingers is as short as 1.6 μ m …
