Linear dichroic x-ray absorption response of Ti-Ti dimers along the axis in TiO upon Mg substitution
M. Okawa, D. Takegami, D. S. Christovam +9
Corundum oxide TiO shows the metal-insulator transition around 400-600 K accompanying the nearest Ti-Ti bond ( singlet state) formation along th…
Neel tensor torque at the ferromagnet/antiferromagnet interface
Chao-Yao Yang, Sheng-Huai Chen, Chih-Hsiang Tseng +3
Antiferromagnets (AFMs) exhibit spin arrangements with no net magnetization, positioning them as promising candidates for spintronics applications. While electrical manipulation of…
Fe substitution in URuSi: singlet magnetism in an extended Doniach phase diagram
Andrea Marino, Denise S. Christovam, Chun-Fu Chang +13
The application of pressure as well as the successive substitution of Ru with Fe in the hidden order (HO) compound URuSi leads to the formation of the large moment antiferr…
Ba2NiOsO6: A Dirac-Mott insulator with ferromagnetism near 100 K
Hai L. Feng, Stuart Calder, Madhav Prasad Ghimire +14
The ferromagnetic semiconductor Ba2NiOsO6 (Tmag ~100 K) was synthesized at 6 GPa and 1500 °C. It crystallizes into a double perovskite structure [Fm-3m; a = 8.0428(1) Å], where the…
State of Co and Mn in half-metallic ferromagnet CoMnSi explored by magnetic circular dichroism in hard X-ray photoelectron emission and soft X-ray absorption spectroscopies
Gerhard H. Fecher, Daniel Ebke, Siham Ouardi +8
The half-metallic Heusler compound CoMnSi is a very attractive material for spintronic devices because it exhibits very high tunnelling magnetoresistance ratios. This work repo…
k=0 magnetic structure and absence of ferroelectricity in SmFeO3
C. -Y. Kuo, Y. Drees, M. T. Fernández-Díaz +17
SmFeO3 has attracted considerable attention very recently due to the reported multiferroic properties above room-temperature. We have performed powder and single crystal neutron di…
