Abstract

We measured magnetization, specific heat, electron spin resonance, neutron diffraction, and inelastic neutron scattering of CrVMoO7 powder. An antiferromagnetically ordered state appears below TN=26.5±0.8 K. We consider that the probable spin model for CrVMoO7 is an interacting antiferromagnetic spin-32 dimer model. We evaluated the intradimer interaction J to be 25±1 K and the effective interdimer interaction Jeff to be 8.8±1 K. CrVMoO7 is a rare spin dimer compound that shows an antiferromagnetically ordered state at atmospheric pressure and zero magnetic field. The magnitude of ordered moments is 0.73(2)μB. It is much smaller than a classical value ∼3μB. Longitudinal-mode magnetic excitations may be observable in single crystalline CrVMoO7.
