Spin-glass order in infinite-layer nickelate superconductors
ORAL
Abstract
Novel magneto--optical measurements in infinite--layer nickelate superconductors Nd${}_{0.825}$Sr${}_{0.175}$NiO${}_2$ and La${}_{0.8}$Sr${}_{0.2}$NiO${}_2$ unveil onset of spin-glass order at temperatures $T_f$ much higher then superconducting critical temperature $T_c$. Large variation in magnitude and onset temperature of magnetic signal in Nd${}_{0.825}$Sr${}_{0.175}$NiO${}_2$ samples fabricated on different substrates is observed.
