Description

The magnetic ground state of the A-site ordered chromium perovskites, ACu3Cr4O12 with A = Y, La, Eu, and Lu has been investigated with μ+SR using powder samples prepared by a high-pressure technique. Weak transverse field measurements revealed that the four compounds enter into a magnetic phase below 230-260 K. Moreover, the transition temperature (TN) was found to decrease with increasing the size of A3+ ions. Zero field measurements indicated the formation of static antiferromagnetic (AF) order in ACu3Cr4O12 below TN. Furthermore, since the internal magnetic field in the AF phase is independent of A, the role of 4f electrons on the AF state is very limited and/or eventually absence in ACu3Cr4O12. (author)
