Optical Magnetoelectric Resonance in a Polar Magnet (Fe,Zn)_{2}Mo_{3}O_{8} with Axion-Type Coupling.

Physical review letters

Kurumaji T, Takahashi Y, Fujioka J, Masuda R, Shishikura H, Ishiwata S, Tokura Y.
PMID: 28949678
Phys Rev Lett. 2017 Aug 18;119(7):077206. doi: 10.1103/PhysRevLett.119.077206. Epub 2017 Aug 18.

We report the polarization rotation of terahertz light resonant with the magnetoelectric (ME) spin excitation in the multiferroic (Fe,Zn)_{2}Mo_{3}O_{8}. This resonance reflects the frequency dispersion of the diagonal ME susceptibility (axion term), with which we quantitatively reproduce the thermal...

PURPOSE: We previously reported that α- and β-blockers protected against emotional stress-induced cardiac dysfunction, but the protective effects of other antihypertensive drugs is unknown. The purpose of this study is to evaluate the ability of a calcium channel blocker,...

Synthesis of styrenes using ruthenium-catalyzed ring-closing enyne metathesis.

Organic letters

Physiol Int. 2021 Jun 29; doi: 10.1556/2060.2021.00147. Epub 2021 Jun 29.

INTRODUCTION: Exercise training is beneficial for reducing obesity. In particular, exercise training can lower the catecholamine concentration in circulation. Renalase, whose expression was first confirmed in the kidneys, is a physiologically active substance that decomposes circulating catecholamines; additionally, it...
