Negative thermal expansion, lattice dynamics, and complex magnetism in TbFeO${}_3$

Shubham Farswan, Reshma Kumawat, Dipankar Sarkar +4

We report a temperature-dependent investigation of orthoferrite TbFeO${}_3$ using x-ray diffraction, DC magnetization, and Raman scattering, complemented by room-temperature x-ray ph…
