Title: Magnetic properties of the itinerant ferromagnet LaCrGe 3 under pressure studied by La 139 NMR

Journal Article · · Physical Review B

139La nuclear magnetic resonance (NMR) measurements under pressure (p = 0 – 2.64 GPa) have been carried out to investigate the static and dynamic magnetic properties of the itinerant ferromagnet LaCrGe3. 139La -NMR spectra for all measured pressures in the ferromagnetically ordered state show a large shift due to the internal field induction |Bint| ~ 4 T at the La site produced by Cr ordered moments. The change in Bint by less than 5% with p up to 2.64 GPa indicates that the Cr 3d moments are robust under pressure. The temperature dependence of NMR shift and Bint suggest that the ferromagnetic order develops below ~50 K under higher pressures in a magnetic field of ~7.2 T. Based on the analysis of NMR data using the self-consistent-renormalization (SCR) theory, the spin fluctuations in the paramagnetic state well above TC are revealed to be three-dimensional ferromagnetic throughout the measured p region.
