We report in the present talk recent results of the tensor properties of the nucleon within the framework of the chiral quark-soliton model. The tensor and anomalous tensor magnetic form factors are calculated for the momentum transfer up to Q2≤1GeV2 and at a renormalization scale of 0.36GeV2. The main results are summarized as follows: the flavor tensor charges of the nucleon are yielded as δu=1.08, δd=−0.31, δs=−0.01, while the up and down anomalous tensor magnetic moments are evaluated as κTu=3.56 and κTd=1.83, respectively. The strange anomalous tensor magnetic moment turns out to be κTs=0.2∼−0.2, compatible with zero. We discuss their physical implications, comparing them in particular with those from the lattice QCD.
