“…LaCrSb 3 crystallizes in an orthorhombic structure (space group P bcm), where Cr occupies one single crystallographic site 4c [19]. Extensive investigations into LaCrSb 3 have been undertaken, and the compound is found to have a rich magnetic phase diagram [18,[20][21][22][23]. LaCrSb 3 exhibits unconventional magnetic behavior with a canted ferromagnetism in bc-plane.…”

“…As La is not moment-bearing, the Cr ion plays the primary role in the magnetism of LaCrSb 3 . Band structure calculations and the X-ray photoelectron spectroscopy studies find that the 3d electrons of the Cr exhibit a large DOS peak at/near the Fermi level in the paramagnetic state [22][23][24], which, based on the Stoner criterion, has a possibility of inducing the ferromagnetic instability.…”

To explore the possibility of quantum phase transitions and even quantum criticality in LaCrSb 3 based compounds, we performed measurements under pressure as well as a vanadium substitution study. The Curie temperature of LaCrSb 3 was found to be invariant under pressure. Although pressure was not able to suppress the ferromagnetism, chemical substitution was used as another parameter to tune the magnetism. We grew La(VxCr 1−x )Sb 3 (x = 0 -1.0) single crystals, and studied the series by measurements of temperature and field dependent magnetic susceptibility, magnetization, resistivity, and specific heat. Ferromagnetism has been observed for x ≤ 0.22, and the system manifests a strong anisotropy in its ordered state. The Curie temperature decreases monotonically as the V concentration increases. For 0.42 ≤ x ≤ 0.73, the system enters a new magnetic state at low temperatures, and no magnetic ordering above 1.8 K can be observed for x ≥ 0.88. The effective moment µ eff /Cr varies only slightly as the V concentration increases, from 3.9 µ B for x = 0 to 2.9 µ B for x = 0.88. Features related to quantum criticality have not been observed in the La(VxCr 1−x )Sb 3 system.

“…A spin reorientation in the bc-plane near 95 K also exists, which can be suppressed with a small field of approximately 250 Oe [7,11]. The magnetic structure is nontrivial and has been studied with neutron diffraction, µSR, x-ray photoelectron spectroscopy, as well as various theoretical models, which have shown coexisting ferromagnetic and antiferromagnetic sublattices below T C [6,[11][12][13][14]. Chemical substitution on the Cr site with V, Mn, Fe, Cu, and Al has been performed and shows a general suppression of the ordering temperature with substitution [15,16].…”

We have performed an extensive pressure-dependent structural, spectroscopic, and electrical transport study of LaCrSb3. The ferromagnetic phase (TC = 120 K at p = 0 GPa) is fully suppressed by p = 26.5 GPa and the Cr-moment decreases steadily with increasing pressure. The unit cell volume decreases smoothly up to p = 55 GPa. We find that the bulk modulus and suppression of the magnetism are in good agreement with theoretical predictions, but the Cr-moment decreases smoothly with pressure, in contrast to steplike drops predicted by theory. The ferromagnetic ordering temperature appears to be driven by the Cr-moment.Notice: This manuscript has been authored in part by UT-Battelle, LLC, under contract DE-AC05-00OR22725 with the US Department of Energy (DOE).
