Tracing the horizon of tetragonal-to-monoclinic distortion in pressurized trilayer nickelate La4Ni3O10
Sitaram Ramakrishnan, Yingzheng Gao, Valerio Olevano +18
The crux of understanding the superconducting mechanism in pressurized Ruddlesden-Popper nickelates hinges on elucidating their structural phases. Under ambient conditions, the tri…
Broken inversion symmetry in the charge density wave phase in EuAl
Surya Rohith Kotla, Leila Noohinejad, Preeti Pokhriyal +4
EuAl exhibits a complex phase diagram, including the development of a charge density wave (CDW) below K. Below K, a series of antiferromagnetically…
I-centered vs F-centered orthorhombic symmetry and negative thermal expansion of the charge density wave of EuAl2Ga2
Harshit Agarwal, Surya Rohith Kotla, Leila Noohinejad +8
Together with EuGa4 and EuAl4, EuAl2Ga2 belongs to the BaAl4 structure type with space group symmetry I4/mmm. EuAl2Ga2 develops an incommensurate charge density wave (CDW) at tempe…
Charge density wave with suppressed long-range structural modulation in canted antiferromagnetic kagome FeGe
Chenfei Shi, Wenchang Hou, Hanbin Deng +30
Kagome lattice can host abundant exotic quantum states such as superconductivity and charge density wave (CDW). Recently, successive orders of A-type antiferromagnetism (AFM), CDW…
Room temperature charge density wave in a tetragonal polymorph of Gd2Os3Si5 and study of its origin in the RE2T3X5 (RE = Rare earth, T = transition metal, X = Si, Ge) series
Vikash Sharma, Sitaram Ramakrishnan, S. S. Jayakrishnan +9
Charge density wave (CDW) systems are proposed to exhibit application potential for electronic and optoelectronic devices. Therefore, identifying new materials that exhibit a CDW s…
Non-centrosymmetric, transverse structural modulation in SrAl4, and elucidation of its origin in the BaAl4 family of compounds
Sitaram Ramakrishnan, Surya Rohith Kotla, Hanqi Pi +13
At ambient conditions SrAl4 adopts the BaAl4 structure type with space group I4/mmm. It undergoes a charge-density-wave (CDW) transition at TCDW = 243 K, followed by a structural t…
