Entropy-Driven Altermagnetism from Thermal Magnons
Tanaya Halder, Ashis K. Nandy, Anamitra Mukherjee
We identify a route to altermagnetism driven by entropy upon heating and demonstrate it in a minimal square-lattice antiferromagnet. An exchange modulation is entropically favored…
Ultrafast Critical Slowing of Spin Dynamics and Emergent Nonequilibrium Fano Interference in Fe3GeTe2
Anupama Chauhan, Sidhanta Sahu, Satyabrata Bera +5
FeGeTe is a prototypical metallic van der Waals ferromagnet with itinerant magnetism and a highly tunable Curie temperature, yet how electronic excitations couple to spin a…
Frustrated magnetic order in hybrid Kitaev spin-orbital models
Ivan Dutta, Aayush Vijayvargia, Anamitra Mukherjee +2
Spin-orbital generalization of Kitaev model provides a robust extension to the original Kitaev model. However, real materials often exhibit competing interactions that break exact…
Correlation-Driven Orbital Order Realizes 2D Metallic Altermagnetism
Nirmalya Jana, Atasi Chakraborty, Anamitra Mukherjee +1
Two-dimensional metallic altermagnets are rare, and no correlated 2D material has been established to host large nonrelativistic spin splitting. Here we show that spontaneous orbit…
