Ultrafast optical manipulation of magnetic phenomena is an exciting achievement of mankind, expanding one’s horizon of knowledge towards functional non-equilibrium states. The dynamics acting on an extremely short timescale push the limit of detect

Using single crystal neutron diffraction, we confirmed the existence of the commensurate transverse helical ordering in B a 0.52 Sr 2.48 C o 2 F e 24 O 41 upon zero-field cooling, in which room-temperature magnetoelectric coupling has been previously

In this study, it is proposed and demonstrated that highly tunable magnetoelectric (ME) response can be achieved from magnetostrictive/piezoelectric laminate composites by integrating the effects of size variation and piezoelectric anisotropy. Tri-la

The Fe3+ and Co2+ NMR spectra for Ba0.3Sr1.7Co2(Fe0.96Al0.04)12O22 (BSCFAO) and Ba0.3Sr1.7Co2Fe12O22 (BSCFO) were obtained in a zero magnetic field at a low temperature. We observed change in the enhancement effect of the NMR signals depending on the

In this Letter, we report the effect of replacing Mn2+ ions with Ni2+ on the ferroelectricity of multiferroic MnWO4 single crystals. When the amount of substitution was close to 16%, the sign of ferroelectric polarization spontaneously became negativ

The magnetocaloric effect (MCE) associated with the spin transitions of alternating longitudinal conical (ALC)-mixed conical (MC) and MC-ferrimagnetic (FIM) states in a Ba0.3Sr1.7Co2Fe12O22 single crystal has been investigated. For magnetic field dir
