Query: Magnetic properties of the itinerant ferromagnet LaCrGe3 under pressure
  studied by 139La NMR   $^{139}$La 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 LaCrGe$_3$. $^{139}$La-NMR
spectra for all measured pressures in the ferromagnetically ordered state show
a large shift due to the internal field induction $|$$B_{\rm int}$$|$ $\sim$ 4
T at the La site produced by Cr ordered moments. The change in $B_{\rm int}$ by
less than 5\% with $p$ up to 2.64~GPa indicates that the Cr 3$d$ moments are
robust under pressure. The temperature dependence of NMR shift and $B_{\rm
int}$ suggest that the ferromagnetic order develops below $\sim$ 50~K under
higher pressures in a magnetic field of $\sim$ 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 $T_{\rm C}$ are revealed to
be three dimensional ferromagnetic throughout the measured $p$ region.
