Exploring switchable altermagnets in TMDCs
ORAL
Abstract
Discovering unique current pulse-induced transverse resistance switching behavior is an integral step towards realizing novel spintronics. This has been recently discovered in intercalated transition metal dichalcogenides (TMDCs), such as in FexNbS2, and thought to originate from a Rashba-type spin-polarized band splitting mechanism [1]. We investigate related magnetically intercalated TMDCs for various magnetic intercalations around x=⅓. The x = ⅓ doping has symmetries consistent with altermagnetism and therefore is of substantial interest for such studies. Using magnetization, heat capacity, and electrical transport measurements under an applied field, we discuss the physical properties of these materials as a function of composition and present results on its ability for pulse-induced transverse resistance switching.
