  A approach for two-dimensional(2D) negative permeability in a $\Lambda$-type
three-level atomic system interacting with a probe magnetic and the
superposition of two orthogonal standing-wave fields is proposed. Through the
theoretical analysis and numerical simulation, two equally and tunable peak
maxima of negative magnetic responses are observed in the x-y plane, and around
the peak maxima region the negative permeability is isotropic. A new avenue to
2D isotropic negative
