Exchange anisotropy-driven noncollinear magnetism and magnetic transitions in MnTiO3 ilmenite
Srimal Rathnayaka, Luke Daemen, Despina Louca
Evidence for multiple magnetic transitions and unconventional spin exchange interactions in the ilmenite insulator MnTiO3 is provided via neutron scattering. On cooling, while G-ty…

Magnetic dynamics in NiTiO3 honeycomb antiferromagnet using neutron scattering
Srimal Rathnayaka, Luke Daemen, Tao Hong +6
The ilmenite NiTiO3 consists of a buckled honeycomb lattice, with the Ni spins aligned ferromagnetically in-plane and antiferromagnetically out-of-plane. Using neutron spectroscopy…

Layer buckling and absence of superconductivity in LaNiO2
S. Rathnayaka, S. Yano, K. Kawashima +4
The recent observation of unconventional superconductivity in thin films of LaNiO2 (critical temperature, Tc~10 K) and in bulk single crystals of La3Ni2O7 (327) under pressure (Tc~…
