Key Points

To explore how Cu substitution affects magnetic order and spin-exciton interactions in MnPSe3.
Investigated Cu-substituted MnPSe3 with varying x values (0 to 0.2)
Conducted comprehensive analyses of magnetic and excitonic properties
Utilized layered van der Waals semiconductor characteristics in the study.
Unique interplay between chemical substitution and magnetism observed
Enhanced excitonic interactions linked to Cu content
Behavior changes as a function of Cu substitution level.

Implication

Investigates magnetic properties in a layered semiconductor, implicating Cu's effect on excitonic behavior.

Abstract

We report a comprehensive investigation of Cu-substituted MnPSe 3 [Mn 1-x Cu 2x PSe 3 (x = 0 -0.2)], a layered van der Waals magnetic semiconductor, revealing a unique interplay between chemical substitution, magnetism, and excitonic...
