Unconventional metallic magnetism in LaCr$_{\mathrm{1-x}}$V$_{\mathrm{x}}$Sb$_{3}$ system

ORAL

Abstract

Unconventional, low temperature ground states can often be found in the vicinity of a magnetic phase transition that has been continuously tuned to 0 K. As part of our search for exotic superconductivity, we have studied the LaCrSb$_{3}$ system. Whereas magnetization measurements of LaCrSb$_{3}$ under pressure reveal no change of $T_{\mathrm{C}}$ up to $\approx $ 5 GPa, the ferromagnetic transition is gradually suppressed with increasing V substitution. Single crystals of the LaCr$_{\mathrm{1-x}}$V$_{\mathrm{x}}$Sb$_{3}$ series have been characterized by measurements of, temperature dependent magnetic susceptibility, magnetization, electrical resistivity, and specific heat. Determinations of magnetic anisotropies as well as ferromagnetic ordering temperatures have been made. Below $T_{\mathrm{C}}$, spin reorientation has been observed within \textit{bc} plane. A $T$ -- $x$ phase diagram has been assembled to shed light on the magnetism in this system.
