説明

We have investigated the magnetic properties of the new colossal magnetoresistance oxide NaCr2O4 with the calcium-ferrite-type structure by using 23Na, 53Cr nuclear magnetic resonance (NMR) and magnetization measurements. This chromate is found to show an antiferromagnetic order with the spin moments slightly canted from the b axis at temperatures below T N=125 K. The spin structure may be governed by the competition between double-exchange ferromagnetic and superexchange antiferromagnetic interactions in the double chains. The origin of the large magnetoresistance is discussed for several scenarios such as phase separation, rearrangement of the spin structure induced by the magnetic field, and domain walls.
