Sažetak
We present an experimental investigation of the magnetic structure in a tetramer system SeCuO3 using neutron powder di raction and nuclear resonance techniques. We establish a commensurate antiferromagnetic ordering with a propagation vector k = (0 ; 0 ; 1). The order parameter follows a critical behavior near TN = 8 K, with a critical exponent beta = 0.32 in agreement with a 3D universality class. Evidence is presented that a singlet state starts to form on tetramers at temperatures as high as 200 K, and its signature is preserved within the ordered state through a strong renormalization of the ordered magnetic moment on two non-equivalent copper sites, m(Cu1) ~  0.35 uB and m(Cu2) < 0.8 uB at 1.5 K.
