WebAug 3, 2024 · CrSBr crystallizes in the orthorhombic Pmmn space group. The structure is two-dimensional and consists of one CrSBr sheet oriented in the (0, 0, 1) direction. Cr3+ is bonded to four equivalent S2- and two equivalent Br1- atoms to form a mixture of corner and edge-sharing CrS4Br2 octahedra. The corner-sharing octahedral tilt angles are 22°. WebSep 1, 2024 · The centimeter-size bulk CrSBr crystals were synthesized by using a chemical vapor transport method (see Experimental Section). As reported in Figure 1a, …
WebApr 3, 2024 · Meanwhile, because of a relatively high Néel temperature (T N) of CrSBr, a sizable TMR of about 50% was observed at 130 K, which makes a big step towards the spintronic devices at room temperature. Our results reveal the potential of realizing magnetic information storage in CrSBr-based spin-filter MTJs (sf-MTJs). WebFig. 1e presents the room temperature photoluminescence (PL) and differential reflectance spectra of CrSBr flakes with 1-3 layer thickness (see Fig. S5 for PL from bulk crystal).
