Description:
(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- 3/2 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.
