Electrically Tunable Heliconical Smectic Superstructure in Polar Fluids
Hiroya Nishikawa, Dennis Kwaria, Atsuko Nihonyanagi +3
The ferroelectric nematic (NF) phase and related polar liquid-crystalline phases form a new class of strongly polarized yet fluid soft matter. Well-recognized heliconical ferroelec…
Three-Dimensional Hieratical Twists in Polar Fluids: Chirality Regulation by Ultra-Low Electric Field
Hiroya Nishikawa, Dennis Kwaria, Atsuko Nihonyanagi +1
Recently discovered helical polar fluid adopts a spontaneous chiral symmetry breaking (CSB) driven by polarization escape and conformational chirality. Ferroelectric nematic and sm…
Spontaneous Twist of Ferroelectric Smectic Blocks in Polar Fluids
Hiroya Nishikawa, Yasushi Okumura, Dennis Kwaria +2
In soft matter, the polar orientational order of molecules can facilitate the coexistence of structural chirality and ferroelectricity. The ferroelectric nematic (NF) state, exhibi…
Emergent Ferroelectric Nematic and Heliconical Ferroelectric Nematic States in an Achiral "Straight" Polar Rod Mesogen
Hiroya Nishikawa, Daichi Okada, Dennis Kwaria +4
Ferroelectric nematic liquid crystals (NFLCs) are distinguished by their remarkable polarization characteristics and diverse physical phenomena, sparking significant interest and e…
Nano-Clustering Mediates Phase Transitions in a Diastereomerically-Stabilized Ferroelectric Nematic System
Hiroya Nishikawa, Koki Sano, Saburo Kurihara +4
During the last half-decade, a new class of ferroic-fluid, ferroelectric nematic liquid crystals (NFLCs), creates a noise owing to its exceptional properties such as a colossal pol…
Current-in-plane magnetoresistance in chiral-molecule/ferromagnetic metal bilayer due to thermally induced spin polarization
Kouta Kondou, Masanobu Shiga, Shoya Sakamoto +7
We report chirality-induced current-in-plane magnetoresistance (CIP-MR) in chiral molecule/ferromagnetic metal bilayer at room temperature. The previously reported chiralityinduced…
Chirality-induced effective magnetic field in a phthalocyanine molecule
Shinji Miwa, Kouta Kondou, Shoya Sakamoto +4
Chirality in organic molecules has attracted considerable attention in the fields of chemistry, biology, and spintronics. This paper reports on perpendicular magnetization hysteres…
