The paper will be presented in The XXVII IUPAC CCP Conference 2015, held in IIT Guwahati India, 2-5 Dec 2015. Spin glass (SG) is a typical magnetic system which is mainly characterized by a frozen random spin orientation at low temperatures. Frustration and randomness are considered to be the key ingredients for the existence of SGs. Previously, Bartolozzi et al. [Phys. Rev. B73, 224419 (2006)] found that the antiferromagnetic (AF) Ising spins on scale free network (SFN) exhibited SG behavior. This is a new type of SG, which is purely AF system, different from the canonical one which requires the presence of both FM and AF couplings. In this new system, frustration is purely due to a topological factor and its randomness is brought by irregular connectivity. Recently, Surungan et. al. [2] reported SG behavior of AF Heisenberg model on SFN. In order to acommodate the notion of spatial dimension, we further investigated this type of system by studying an AF Heisenberg model on rewired cubic lattices, i.e., by adding one extra bond randomly connecting a spin to one of its next-nearest neighbors . We used Replica Exchange algorithm of Monte Carlo Method [3] and calculated the SG order parameter to search for the existence of SG phase. References: 1. M. Bartolozzi, T. Surungan, D.B.
