Real-space determination of orbital states driving successive phase transitions in FeV2O4
Chihaya Koyama, Yusuke Nomura, Shunsuke Kitou +8
Direct experimental access to orbital states in strongly correlated materials remains a major challenge, despite their central role in driving coupled structural and magnetic phase…
Microwave impedance microscopy imaging of acoustic topological edge mode on a patterned substrate
Yoichi Nii, Yoshinori Onose
We have studied acoustic topological edge modes in a honeycomb phononic crystal composed of metallic nano-pillars on a LiNbO substrate. Acoustic band calculations show that the…
Elastic study of electric quadrupolar correlation in the paramagnetic state of a frustrated quantum magnet
Y. Nii, Y. Hirokane, S. Nakamura +4
Electric quadrupolar state in a frustrated quantum magnet has been studied by means of ultrasonic and magnetostriction measurements. A single crys…
Chirality memory stored in magnetic domain walls in the ferromagnetic state of MnP
N. Jiang, Y. Nii, H. Arisawa +2
Chirality in a helimagnetic structure is determined by the sense of magnetic moment rotation. We found that the chiral information did not disappear even after the phase transition…
Magnetotransport properties in a noncentrosymmetric itinerant magnet CrGe
N. Jiang, Y. Nii, R. Ishii +2
We have investigated anomalous Hall effect and magnetoresistance in a noncentrosymmetric itinerant magnet CrGe. While the temperature- and magnetic-field-dependent an…
