Its zero-field NMR has been observed at 4.2 K and 77 K as a function of pressure. Under atmospheric pressure at 4.2 K, 55^Mn and 75^As NMR are observed at 236 and 208 MHz,respectively. Above approximately 4 kbar at 4.2 K and 77 K, a broad NMR line, where 55^Mn NMR overlaps with 75^As NMR, is observed within the region from 140 to 200 MHz and assigned to the double helical magnetic MnP-type phase induced by applying pressure. It suggests that the Mn spins in Mn_0.97Cr_0.03 As take the value nearly close to a low spin state in MnP-type phase under high pressure.}, pages = {43--50}, title = {Mn_0.97 Cr_0.03 ASの高圧下NMR}, year = {2016} }
