Magnetic properties of a cupric triangular cluster compound La 4 Cu 3 MoO 12 were
investigated. Susceptibility data show that paramagnetic cupric spin (S= 1 2) above room
temperature forms S= 1 2 trimers at lower temperatures because of strong intratrimer
antiferromagnetic interactions. The cluster moments acquire antiferromagnetic order below
2.6 K. The trimers can be polarized in an external field of 20 T at 1.3 K. The magnetization
remains nearly constant at 1 μ B per trimer up to a magnetization plateau at 55 T.

Abstract
Magnetic properties of a cupric triangular cluster compound La 4 Cu 3 MoO 12 were investigated. Susceptibility data show that paramagnetic cupric spin (S= 1 2) above room temperature forms S= 1 2 trimers at lower temperatures because of strong intratrimer antiferromagnetic interactions. The cluster moments acquire antiferromagnetic order below 2.6 K. The trimers can be polarized in an external field of 20 T at 1.3 K. The magnetization remains nearly constant at 1 μ B per trimer up to a magnetization plateau at 55 T.
