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 Q{sup 2}{<=}1 GeV{sup 2} and at a renormalization scale of 0.36 GeV{sup 2}. The main results are summarized as follows: the flavor tensor charges of the nucleon are yielded as {delta}u = 1.08, {delta}d = -0.31, {delta}s -0.01, while the up and down anomalous tensor magnetic moments are evaluated as {kappa}{sub T}{sup u} = 3.56 and {kappa}{sub T}{sup d} = 1.83, respectively. The strange anomalous tensor magnetic moment turns out to be {kappa}{sub T}{sup s} 0.2{approx}-0.2, compatible with zero. We discuss their physical implications, comparing them in particular with those from the lattice QCD.
